rd (route distinguisher)
Use this command to assign a route distinguisher (RD) for the VRF. The route distinguisher value must be a unique value on the router.
This command creates routing and forwarding tables and specifies the default RD for a VPN. The RD is added to the customer's IPv4 prefixes, changing them into globally unique VPN-IPv4 prefixes.
Use no form command to remove the RD configuration.
Note: RD configuration cannot be changed, it needs to be removed and added back with new value. When RD configuration is removed the RT configuration is also lost and needs to be reconfigured.
