route-distinguisher (MPLS L2VPN view)

Syntax	route-distinguisher route-distinguisher
View	MPLS L2VPN view
Parameter	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.
Description	Use the route-distinguishercommand to configure an RD for the VPN.
	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.
Example	# Configure the RD of a VPN.
