The Cloud Router custom learned routes feature is in Preview. This feature lets you configure a Border Gateway Protocol (BGP) session to include learned routes that you manually specify. Cloud Router then behaves as if it learned the routes from the BGP peer.
Custom learned routes can be helpful if you want to avoid the limitations of static routes. For example:
Static routes can't detect a loss of reachability in the next hop of a route. In contrast, custom learned routes can detect a loss of reachability, and they react accordingly to avoid dropping traffic without notification.
Static routes do not support using HA VPN tunnels or Cloud Interconnect VLAN attachments as next hops. Custom learned routes do.
For more information, see Custom learned routes.

Cloud Router supports Multiprotocol BGP (MP-BGP) and can exchange IPv6 prefixes over IPv4 BGP sessions. Cloud Router supports IPv6 prefix advertisement for VPC networks with dual-stack subnets. You can enable IPv6 prefix exchange over IPv4 BGP sessions that are created for HA VPN tunnels. This feature is generally available.
