Amazon Web Services Networkmanager Connect Peer: A Deep Dive in AWS Resources & Best Practices to Adopt
Modern enterprises are increasingly adopting hybrid and multi-cloud architectures, with 92% of organizations using a multi-cloud strategy according to the 2024 State of the Cloud Report. As these complex network topologies grow, managing connectivity between AWS environments and on-premises infrastructure becomes a critical challenge. Traditional VPN connections and Direct Connect often fall short when organizations need dynamic routing capabilities and seamless integration with their existing network infrastructure.
Amazon Web Services recognizes this challenge and has developed sophisticated networking solutions to bridge the gap between cloud and on-premises environments. The AWS Network Manager Connect Peer represents a significant advancement in this space, providing organizations with the ability to establish BGP-based peering connections that enable dynamic routing updates and scalable network architectures.
Network connectivity requirements have evolved dramatically over the past decade. Organizations are no longer satisfied with static routing configurations that require manual updates and lack the flexibility needed for modern distributed applications. They need solutions that can automatically adapt to changing network conditions, provide redundancy, and maintain optimal performance across geographically distributed resources. This is where the Networkmanager Connect Peer becomes an invaluable component of enterprise network architecture.
In this blog post we will learn about what Networkmanager Connect Peer is, how you can configure and work with it using Terraform, and learn about the best practices for this service.
What is Networkmanager Connect Peer?
Networkmanager Connect Peer is an AWS service that enables organizations to establish BGP (Border Gateway Protocol) peering connections between their AWS transit gateways and external network infrastructure. This service acts as a bridge that allows dynamic routing information to be exchanged between AWS cloud resources and on-premises or third-party network equipment, creating a unified network topology that can adapt to changing conditions automatically.
The service operates within the AWS Network Manager ecosystem, which provides centralized network management capabilities across multiple AWS accounts and regions. When you create a Connect Peer, you're establishing a logical connection point that speaks BGP protocol, allowing your network equipment to exchange routing information with AWS infrastructure in real-time. This creates a more intelligent and responsive network architecture compared to traditional static routing approaches.
At its core, the Networkmanager Connect Peer service transforms how organizations think about network connectivity. Instead of manually configuring and maintaining routing tables across multiple network devices, Connect Peer enables automatic route advertisement and learning. This means when new subnets are created in AWS or when network topology changes occur on-premises, the routing information is automatically propagated to all connected devices without manual intervention.
The service integrates seamlessly with AWS Transit Gateway Connect attachments, which serve as the foundation for establishing these BGP peering relationships. This integration ensures that routing information flows smoothly between your AWS environment and external networks, while maintaining the security and performance characteristics that enterprises require for mission-critical applications.
BGP Peering and Dynamic Routing Capabilities
BGP peering through Networkmanager Connect Peer represents a fundamental shift from traditional static routing approaches. When you establish a Connect Peer, you're creating a dynamic communication channel that continuously exchanges routing information between your AWS environment and external networks. This exchange happens through BGP sessions that maintain persistent connections between your network equipment and AWS infrastructure.
The BGP implementation in Connect Peer supports both IPv4 and IPv6 routing, allowing organizations to deploy modern dual-stack network architectures. Each Connect Peer can maintain multiple BGP sessions simultaneously, providing redundancy and load distribution across different network paths. This capability is particularly valuable for organizations with geographically distributed infrastructure that requires optimal routing between multiple locations.
Route advertisement through Connect Peer is bidirectional, meaning both AWS and your external network can announce routes to each other. AWS can advertise routes for VPC subnets, other AWS services, and even routes learned from other Connect Peers or VPN connections. Similarly, your external network can advertise routes for on-premises resources, branch offices, or third-party cloud environments, creating a comprehensive view of your entire network topology.
The service also supports advanced BGP features such as route filtering, route maps, and community attributes. These features allow network administrators to implement sophisticated routing policies that control how traffic flows between different network segments. For example, you can configure route filters to prevent certain routes from being advertised to specific peers, or use community attributes to influence routing decisions based on business priorities or security requirements.
BGP session management in Connect Peer includes automatic failover capabilities. If a BGP session fails due to network issues or equipment problems, the service can automatically redirect traffic to alternative paths while continuously attempting to reestablish the failed connection. This self-healing capability reduces the impact of network failures on application performance and provides the resilience that modern distributed applications require.
Network Manager Integration and Global Network Topology
The integration between Networkmanager Connect Peer and AWS Network Manager creates a unified view of your global network topology that spans multiple AWS regions, accounts, and external networks. This integration is more than just a management interface; it provides operational insights and control capabilities that transform how network teams monitor and manage complex network environments.
Through Network Manager, Connect Peer configurations become part of a global network map that shows the relationships between different network components. This visualization includes not only the Connect Peer connections themselves but also the Transit Gateway attachments, VPC connections, and external network links that make up your complete network topology. This comprehensive view helps network teams understand traffic flows, identify potential bottlenecks, and plan for network expansion or optimization.
The global network topology maintained by Network Manager also enables centralized monitoring and troubleshooting capabilities. Network administrators can track BGP session status, monitor route advertisement patterns, and identify connectivity issues across their entire network infrastructure from a single management interface. This centralized approach reduces the complexity of managing multi-region, multi-account network deployments and provides the visibility needed for effective network operations.
Network Manager's integration with Connect Peer also supports change management and compliance requirements. All configuration changes to Connect Peer resources are logged and tracked through AWS CloudTrail, providing an audit trail for security and compliance purposes. This logging capability is particularly important for organizations in regulated industries that must maintain detailed records of network configuration changes.
The service also provides APIs and automation capabilities that enable programmatic management of Connect Peer resources. This automation support allows organizations to integrate Connect Peer management into their existing network automation workflows, enabling consistent deployment and configuration management across multiple environments. The ability to automate Connect Peer provisioning and management is especially valuable for organizations implementing Infrastructure as Code practices or managing large-scale network deployments.
Strategic Importance for Modern Network Architecture
The strategic importance of Networkmanager Connect Peer extends far beyond simple connectivity solutions. As organizations migrate to hybrid and multi-cloud architectures, the ability to maintain dynamic, intelligent routing between different network environments becomes a competitive advantage. Research from IDC indicates that organizations with mature network automation capabilities achieve 40% faster application deployment times and 35% lower operational costs compared to those relying on manual network management processes.
Operational Efficiency and Automation
Networkmanager Connect Peer dramatically reduces the operational overhead associated with managing complex network topologies. Traditional approaches to hybrid networking often require network teams to manually configure and maintain routing tables across dozens or hundreds of network devices. Each time a new subnet is created in AWS or when network topology changes occur on-premises, these configurations must be updated manually, creating opportunities for errors and increasing the time required for network changes.
With Connect Peer, this manual process is eliminated through automatic route advertisement and learning. When new resources are deployed in AWS, the routing information is automatically propagated to connected external networks without any manual intervention. Similarly, when on-premises network changes occur, the updated routing information is automatically distributed to AWS infrastructure, ensuring that all network components maintain accurate and current routing tables.
The automation capabilities extend beyond basic route advertisement to include sophisticated traffic engineering and load balancing. Organizations can implement policies that automatically redirect traffic to optimal paths based on real-time network conditions, application requirements, or business priorities. This intelligent traffic management reduces latency, improves application performance, and maximizes the utilization of available network resources.
Cost optimization represents another significant operational benefit. By enabling dynamic routing and automatic failover, Connect Peer reduces the need for over-provisioned network capacity and redundant connections. Organizations can implement more efficient network designs that provide the same level of reliability and performance while reducing overall networking costs. The service also eliminates the need for specialized network management tools and reduces the staffing requirements for network operations teams.
Security and Compliance Advantages
The security architecture of Networkmanager Connect Peer addresses many of the challenges associated with hybrid network connectivity. Unlike traditional VPN solutions that often require complex firewall configurations and manual security policy management, Connect Peer integrates directly with AWS security services to provide comprehensive protection for network traffic.
BGP session authentication and encryption capabilities ensure that routing information exchanges are protected against tampering and eavesdropping. The service supports industry-standard BGP security features including MD5 authentication, route filtering, and prefix validation. These security measures prevent unauthorized devices from participating in BGP exchanges and protect against route hijacking attacks that could redirect traffic to malicious destinations.
Integration with AWS security services extends the security benefits beyond the Connect Peer itself. Traffic flowing through Connect Peer connections can be monitored and analyzed using AWS VPC Flow Logs, AWS GuardDuty, and AWS Security Hub. This integration provides comprehensive visibility into network traffic patterns and enables automated threat detection and response capabilities.
Compliance requirements in regulated industries often mandate specific network security controls and audit capabilities. Connect Peer addresses these requirements through comprehensive logging and monitoring features that track all network configuration changes and routing updates. The service integrates with AWS CloudTrail to provide detailed audit logs that meet the requirements of standards such as SOC 2, PCI DSS, and HIPAA.
Business Continuity and Disaster Recovery
The disaster recovery capabilities enabled by Networkmanager Connect Peer represent a significant advancement in business continuity planning. Traditional network architectures often rely on manual failover processes that can take minutes or hours to complete, resulting in extended application downtime during network failures or disasters.
Connect Peer's automatic failover capabilities can redirect traffic to alternative paths within seconds of detecting a network failure. This rapid failover is achieved through BGP convergence mechanisms that automatically withdraw routes for failed connections and advertise alternative paths. The result is dramatically reduced recovery times and improved application availability during network disruptions.
The service also supports active-active network configurations where traffic is automatically distributed across multiple connection paths. This approach provides both performance benefits through load distribution and resilience benefits through built-in redundancy. Organizations can implement geographically distributed network architectures that maintain full application availability even when entire data centers or network regions become unavailable.
Multi-region disaster recovery scenarios are particularly well-suited to Connect Peer capabilities. Organizations can establish Connect Peer connections in multiple AWS regions, creating a mesh network topology that provides multiple recovery paths for critical applications. This geographic distribution ensures that regional network failures or natural disasters don't compromise the organization's ability to maintain business operations.
Managing Networkmanager Connect Peer using Terraform
Working with Networkmanager Connect Peer through Terraform requires careful planning and understanding of the underlying network architecture. The configuration involves multiple interconnected resources and dependencies that must be properly orchestrated to create a functioning BGP peering connection. The complexity stems from the need to coordinate between AWS Network Manager, Transit Gateway Connect attachments, and the underlying routing infrastructure.
Production Environment with Redundant BGP Peering
For production environments, establishing redundant BGP peering connections provides the reliability and failover capabilities that mission-critical applications demand. This configuration creates multiple Connect Peers across different Availability Zones to ensure continuous connectivity even if one peer experiences issues.
# Transit Gateway Connect Attachment for primary connection
resource "aws_ec2_transit_gateway_connect" "primary" {
transport_attachment_id = aws_ec2_transit_gateway_vpc_attachment.main.id
transit_gateway_id = aws_ec2_transit_gateway.main.id
tags = {
Name = "primary-tgw-connect"
Environment = "production"
Purpose = "bgp-peering"
}
}
# Primary Connect Peer configuration
resource "aws_networkmanager_connect_peer" "primary" {
connect_attachment_id = aws_ec2_transit_gateway_connect.primary.id
peer_address = "10.0.1.100"
bgp_options {
peer_asn = 65001
}
inside_cidr_blocks = ["169.254.101.0/29"]
tags = {
Name = "primary-bgp-peer"
Environment = "production"
AZ = "us-east-1a"
Role = "primary"
}
}
# Secondary Connect Peer for redundancy
resource "aws_networkmanager_connect_peer" "secondary" {
connect_attachment_id = aws_ec2_transit_gateway_connect.primary.id
peer_address = "10.0.2.100"
bgp_options {
peer_asn = 65001
}
inside_cidr_blocks = ["169.254.102.0/29"]
tags = {
Name = "secondary-bgp-peer"
Environment = "production"
AZ = "us-east-1b"
Role = "secondary"
}
}
# CloudWatch alarms for monitoring BGP session health
resource "aws_cloudwatch_metric_alarm" "bgp_session_primary" {
alarm_name = "bgp-session-primary-down"
comparison_operator = "LessThanThreshold"
evaluation_periods = "2"
metric_name = "BgpSessionState"
namespace = "AWS/NetworkManager"
period = "60"
statistic = "Average"
threshold = "1"
alarm_description = "This metric monitors BGP session state for primary peer"
alarm_actions = [aws_sns_topic.network_alerts.arn]
dimensions = {
ConnectPeerId = aws_networkmanager_connect_peer.primary.id
}
}
This configuration establishes a robust production-grade BGP peering setup with monitoring capabilities. The peer_address parameter specifies the IP address of the remote BGP peer, while inside_cidr_blocks defines the point-to-point link subnet used for the BGP session. The BGP ASN (Autonomous System Number) is configured through the bgp_options block, which must match the ASN configured on the remote peer device.
The redundant design ensures that if the primary BGP session fails, traffic can automatically failover to the secondary peer. This configuration requires coordination with your network team to ensure that the remote peer devices are properly configured with matching ASN numbers and IP addressing schemes. The CloudWatch alarm integration provides proactive monitoring of BGP session health, alerting administrators when sessions go down.
Multi-Region BGP Peering with Global Transit Gateway
For organizations with global infrastructure requirements, establishing BGP peering connections across multiple AWS regions provides the foundation for a truly global network. This scenario demonstrates how to create Connect Peers that work with Transit Gateway peering connections to enable inter-region routing.
# Global Transit Gateway in primary region
resource "aws_ec2_transit_gateway" "global_primary" {
amazon_side_asn = 64512
auto_accept_shared_attachments = "enable"
auto_accept_shared_associations = "enable"
description = "Global TGW Primary Region"
tags = {
Name = "global-tgw-primary"
Region = "us-east-1"
Type = "global-hub"
}
}
# Transit Gateway Connect for regional connectivity
resource "aws_ec2_transit_gateway_connect" "regional_hub" {
transport_attachment_id = aws_ec2_transit_gateway_vpc_attachment.regional.id
transit_gateway_id = aws_ec2_transit_gateway.global_primary.id
tags = {
Name = "regional-hub-connect"
Purpose = "inter-region-bgp"
}
}
# Connect Peer for regional data center integration
resource "aws_networkmanager_connect_peer" "regional_dc" {
connect_attachment_id = aws_ec2_transit_gateway_connect.regional_hub.id
peer_address = "192.168.100.1"
bgp_options {
peer_asn = 65100
}
inside_cidr_blocks = ["169.254.200.0/29"]
tags = {
Name = "regional-dc-peer"
DataCenter = "atlanta-dc-01"
Region = "us-east-1"
Purpose = "regional-integration"
}
}
# Route Table Association for regional routing
resource "aws_ec2_transit_gateway_route_table_association" "regional_routes" {
transit_gateway_attachment_id = aws_ec2_transit_gateway_connect.regional_hub.id
transit_gateway_route_table_id = aws_ec2_transit_gateway_route_table.global_routes.id
}
# Prefix List for route filtering
resource "aws_ec2_managed_prefix_list" "regional_prefixes" {
name = "regional-allowed-prefixes"
address_family = "IPv4"
max_entries = 100
entry {
cidr = "10.100.0.0/16"
description = "Regional Office Network"
}
entry {
cidr = "10.200.0.0/16"
description = "Regional Data Center"
}
tags = {
Name = "regional-prefix-list"
Purpose = "bgp-route-filtering"
}
}
This multi-region configuration demonstrates how Connect Peers integrate with Transit Gateway's global routing capabilities. The amazon_side_asn parameter on the Transit Gateway must be unique across your AWS environment and should not conflict with any on-premises ASN numbers. The regional Connect Peer establishes BGP sessions with remote data centers, enabling dynamic route advertisement and optimal traffic flow.
The prefix list configuration provides granular control over which routes are advertised and accepted through the BGP sessions. This is particularly important in multi-region deployments where you need to prevent routing loops and ensure that traffic flows through optimal paths. The Transit Gateway route table association ensures that routes learned through BGP are properly propagated throughout your AWS network infrastructure.
When implementing this configuration, consider the impact on your global routing architecture. The BGP sessions will automatically exchange routing information, which can affect traffic patterns across your entire network. It's recommended to implement this configuration in a phased approach, starting with non-production environments to validate routing behavior before deploying to production.
The monitoring and alerting components are crucial for maintaining visibility into the health of your global network. The CloudWatch integration provides metrics on BGP session state, route counts, and traffic volume, enabling proactive management of your network infrastructure. Consider implementing automated remediation workflows that can respond to BGP session failures by activating backup paths or notifying network operations teams.
Best practices for Networkmanager Connect Peer
Managing Network Manager Connect Peers requires careful planning and implementation to ensure optimal performance, security, and maintainability. These best practices have been developed through real-world deployments and help organizations avoid common pitfalls while maximizing the benefits of BGP-based connectivity.
Implement Redundant Peer Connections
Why it matters: Network failures are inevitable, and single points of failure can cause significant business disruption. BGP peering connections are particularly vulnerable to issues such as ISP outages, hardware failures, or configuration errors. Without redundancy, a single peer failure can isolate entire network segments.
Implementation: Configure multiple Connect Peers across different Availability Zones and use diverse network paths. This approach ensures that if one peer becomes unavailable, traffic can automatically failover to alternative paths through BGP route convergence.
# Create primary peer in us-east-1a

--core-network-address 169.254.101.1 \\
--peer-address 169.254.101.2 \\
--tags Key=Environment,Value=production Key=Role,Value=secondary
Configure BGP route preferences using AS-path prepending or local preference attributes to control traffic flow during normal operations while maintaining the ability to failover quickly. Monitor peer connection health using CloudWatch metrics and set up automated alerts for connection state changes.
Standardize BGP Configuration Parameters
Why it matters: Inconsistent BGP configurations across Connect Peers can lead to routing loops, suboptimal path selection, and difficult troubleshooting scenarios. Standardized configurations ensure predictable behavior and simplify network operations.
Implementation: Establish consistent ASN assignments, route filtering policies, and timer configurations across all Connect Peers. Document your BGP design decisions and maintain configuration templates for different deployment scenarios.
# BGP configuration template
locals {
bgp_config = {
customer_asn = 65001
amazon_asn = 64512
hold_time = 180
keepalive = 60
# Standard route filters
route_filters = {
advertise_default = false
max_prefix_limit = 1000
prefix_filters = [
"10.0.0.0/8",
"172.16.0.0/12",
"192.168.0.0/16"
]
}
}
}
resource "aws_networkmanager_connect_peer" "standard_peer" {
connect_id = aws_networkmanager_connect_attachment.main.id
peer_address = var.peer_address
bgp_options {
asn = local.bgp_config.customer_asn
}
inside_cidr_blocks = [var.inside_cidr_block]
tags = merge(var.common_tags, {
BGPConfig = "standard-v1.0"
ASN = local.bgp_config.customer_asn
})
}
Implement route filtering at the peer level to prevent unwanted route advertisements and protect against route hijacking attempts. Use community strings to tag routes and implement consistent routing policies across your network infrastructure.
Monitor and Alert on BGP Session Health
Why it matters: BGP sessions can experience silent failures or performance degradation that may not be immediately apparent. Proactive monitoring helps identify issues before they impact application performance and enables rapid response to network events.
Implementation: Set up comprehensive monitoring using CloudWatch metrics, custom health checks, and third-party network monitoring tools. Create alerting rules for BGP session state changes, route table modifications, and performance degradation.
# Create CloudWatch alarm for BGP session state
aws cloudwatch put-metric-alarm \\
--alarm-name "BGP-Session-Down-${PEER_ID}" \\
--alarm-description "BGP session down for Connect Peer" \\
--metric-name BgpSessionState \\

--alarm-description "Unexpected route count change" \\
--metric-name AdvertisedRoutes \\
--namespace AWS/NetworkManager \\
--statistic Average \\
--period 300 \\
--threshold 100 \\
--comparison-operator GreaterThanThreshold \\
--evaluation-periods 3
Implement automated response procedures for common BGP issues, such as session flapping or route convergence problems. Create runbooks for network operations teams that include troubleshooting steps and escalation procedures for different types of BGP-related incidents.
Implement Proper IP Address Management
Why it matters: BGP peering requires careful IP address allocation to avoid conflicts and ensure proper routing behavior. Poor IP address management can lead to routing black holes, connectivity issues, and security vulnerabilities.
Implementation: Use dedicated IP address ranges for BGP peering that don't overlap with other network segments. Follow RFC 3021 guidelines for point-to-point links and maintain an IP address management database (IPAM) to track allocations.
# IP address management for Connect Peers
variable "bgp_peer_subnets" {
description = "Dedicated subnets for BGP peering"
type = map(object({
cidr_block = string
az = string
purpose = string
}))
default = {
peer_1 = {
cidr_block = "169.254.100.0/30"
az = "us-east-1a"
purpose = "primary-bgp-peer"
}
peer_2 = {
cidr_block = "169.254.100.4/30"
az = "us-east-1b"
purpose = "secondary-bgp-peer"
}
}
}
resource "aws_networkmanager_connect_peer" "managed_peer" {
for_each = var.bgp_peer_subnets
connect_id = aws_networkmanager_connect_attachment.main.id
peer_address = var.peer_addresses[each.key]
inside_cidr_blocks = [each.value.cidr_block]
bgp_options {
asn = var.customer_asn
}
tags = {
Name = "connect-peer-${each.key}"
Subnet = each.value.cidr_block
Purpose = each.value.purpose
Environment = var.environment
}
}
Document your IP addressing scheme and maintain records of all BGP peer allocations. Use automation tools to validate IP address assignments and detect potential conflicts before they cause connectivity issues.
Secure BGP Communications
Why it matters: BGP sessions carry sensitive routing information and can be targets for network attacks. Unsecured BGP communications can lead to route hijacking, traffic interception, and network instability.
Implementation: Implement BGP authentication using MD5 passwords or more advanced authentication mechanisms where supported. Use network ACLs and security groups to restrict BGP traffic to authorized peers only.
# Configure BGP authentication and security
aws networkmanager create-connect-peer \\
--connect-id $CONNECT_ID \\
--peer-address 10.0.1.100 \\

--description "BGP peering from authorized peer"
Regularly audit BGP configurations for security compliance and implement change control processes for BGP-related modifications. Use network segmentation to isolate BGP control plane traffic from data plane traffic and implement logging for all BGP session activities.
Plan for Capacity and Performance
Why it matters: BGP performance can significantly impact application response times and overall network efficiency. Inadequate capacity planning can lead to route processing delays, session timeouts, and poor user experience during peak traffic periods.
Implementation: Size your Connect Peer deployments based on expected route table sizes, update frequencies, and traffic volumes. Monitor BGP convergence times and optimize configurations for your specific network topology.
