A company has configured an AWS Cloud WAN core network with edge locations in the us-east-1 Region and the us-west-1 Region. Each edge location has two segments: development and staging. The segments use the default core network policy.
The company has attached VPCs to the core network. A development VPC is attached to the development segment in us-east-1 and is configured to use the 10.0.0.0/16 CIDR block. A staging VPC is attached to the staging segment in us-west-1 and is configured to use the 10.5.0.0/16 CIDR block. The company has updated the route tables for both VPCs with a route that directs any traffic for 0.0.0.0/0 to the core network.
The company’s network team needs to establish communication between the two VPCs by using the AWS Cloud WAN core network. The network team is not receiving a response during tests of communication between the VPCs. The network team has verified that security groups and network ACLs are not blocking the traffic.
What should the network team do to establish this communication?
A company has an AWS Site-to-Site VPN connection between AWS and its branch office. A network engineer is troubleshooting connectivity issues that the connection is experiencing. The VPN connection terminates at a transit gateway and is statically routed. In the transit gateway route table, there are several static route entries that target specific subnets at the branch office.
The network engineer determines that the root cause of the issues was the expansion of underlying subnet ranges in the branch office during routine maintenance.
Which solution will solve this problem with the LEAST administrative overhead for future expansion efforts?
