route-distinguisher: Specifies the route distinguisher (RD) in the format of nn:nn or
IP-address:nn. It can be a string of 3 to 21 characters.
An RD can be in either of the following formats:
16-bit AS number:32-bit user-defined number. For example, 101:3.
■
32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
■
Use the route-distinguisher
Different VPNs on a PE must have different RDs, while a VPN can have the same or
different RDs on different PEs.
n
You cannot change an RD directly; you can only delete the VPN and then
■
re-create the VPN using the new RD.
No RD is configured by default; you must configure an RD for each VPN. A VPN
■
takes effect only when it is configured with an RD.
Once you configure an RD for a VPN, you cannot remove the association
■
between the RD and the VPN.
# Configure the RD of a VPN.
