Usage guidelines
RDs enable VPNs to use the same address space. An RD and an IPv4 prefix comprise a unique VPN IPv4
prefix. You can use RDs to identify different BGP VPN instances on an MCE.
To change the RD of a VPN instance, you must delete the RD with the undo route-distinguisher command,
and then use the route-distinguisher command to configure a new RD.

# Configure RD 22:1 for VPN instance vpn1.
