(Optional) Setting a Router ID for a BGP VPN Instance

To distinguish a BGP VPN instance from the other BGP VPN instances on the same device, specify a unique router ID for the BGP VPN instance.

Context

By default, all BGP-VPN instances on a device use the BGP router ID as their router ID. In this case, different BGP-VPN instances on the same device have the same router ID. Using the same router ID for all BGP VPN instances sometimes creates inconveniences. For example, it is impossible to establish a BGP peer relationship between two BGP VPN instances that use the same router ID on a PE.
