VPC Routes

These are the routes associated with VPC vpc-hydra.

The five default routes were created automatically when the VPC was created. The other three routes were learned via BGP from AWS Virtual Private Gateway.

The subnet was learned via two different VPN gateway tunnels from AWS region eu-west-1. Both routes were installed on the routing table since their costs (priorities) are the same – 100. The subnet was learned only via one VPN gateway from AWS region us-east-1.

The next hop IP addresses are for the default routes are towards the GCP VPC or internet gateway.
