route-distinguisher (MPLS-L2VPN instance view)

Function

The route-distinguisher command configures an RD for an MPLS L2VPN instance.

By default, no RD is configured in the MPLS L2VPN instance view.

route-distinguisher route-distinguisher

Parameter	Description	Value
route-distinguisher	Specifies the value of an RD. The formats of an RD are as follows: 16-bit AS number:32-bit user-defined number For example, 102:3. An AS number ranges from 0 to 65535. A user-defined number ranges from 0 to 4294967295. The AS number and the user-defined number cannot be 0s at the same time. That is, an RD cannot be 0:0. 32-bit IP address:16-bit user-defined number For example, 192.168.122.15:1. An IP address ranges from 0.0.0.0 to 255.255.255.255. A user-defined number ranges from 0 to 65535. Integral 4-byte AS number:2-byte user-defined number, for example, 65537:3. An AS number ranges from 65536 to 4294967295. A user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. That is, an RD cannot be 0:0. 4-byte AS number in dotted notation:2-byte user-defined number, for example, 0.0:3 or 0.1:0. A 4-byte AS number in dotted notation is in the format of x.y, where x and y are integers that range from 1 to 65535 and from 0 to 65535, respectively. A user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. That is, an RD cannot be 0.0:0.	-

2: Configuration level

Usage Scenario

In a Kompella VLL networking, an L2VPN instance takes effect only after an RD is configured.

Precautions

VPNs on the same PE have different RDs. The same VPN can have the same RD or different RDs on different PEs.

To change the RD of an L2VPN instance, delete the L2VPN instance and create a new L2VPN instance.

Kompella VLL and Kompella VPLS must use different RDs.
