route-distinguisher: Route distinguisher (RD) for the VPN instance, a string of 3 to 21 characters in 

either of the following two formats: 

z 

16-bit AS number:32-bit user-defined number. For example, 101:3. 

z 

32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1. 

Use the route-distinguisher command to configure a route distinguisher (RD) for a VPN instance.  

An RD is used to create the routing and FIB of a VPN.  By prefixing an RD to an IPv4 prefix, you get a 

VPN IPv4 prefix unique globally. 

 

z 

No RD is configured by default; you must configure an RD for each VPN instance. 

z 

A VPN instance takes effect only after you configure an RD for it.  

z 

Once you configure an RD for a VPN, you cannot remove the association. 

z 

You cannot change an RD directly; you can only delete the VPN instance, and then re-create the 

VPN instance and re-configure a new RD.
