Cloud Router documentation
Cloud Router enables you to dynamically exchange routes between your
Virtual Private Cloud (VPC) and peer network by using
Border Gateway Protocol (BGP).
For example, if you use a Cloud VPN tunnel to connect your networks, you can
use Cloud Router to establish a BGP session with
a router in your peer network over a Cloud VPN tunnel. The peer network
can be an on-premises network, multicloud network, or another VPC network.
Cloud Router automatically learns new subnet IP address ranges in your VPC
network and can announce them to your peer network.
