# Cloud Router documentation

[Read product documentation](https://docs.cloud.google.com/network-connectivity/docs/router/concepts/overview)
Cloud Router enables you to dynamically exchange routes between your
Virtual Private Cloud (VPC) and peer network by using
[Border Gateway Protocol (BGP)](https://www.wikipedia.org/wiki/Border_Gateway_Protocol).


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.
