route-distinguisher (VSI-BGP-MH view)

Function

The route-distinguisher command configures an RD for a VSI.

The undo route-distinguisher command deletes the RD of a VSI.

By default, no RD is configured for a VSI.

Format

route-distinguisher rdValue

Parameters

Parameter	Description	Value
rdValue	Specifies an RD for a VSI.	The available RD formats are as follows: 2-byte AS number:4-byte user-defined number, such as 101:3. The AS number ranges from 0 to 65535, and the user-defined number ranges from 0 to 4294967295. The AS number and user-defined number cannot be both 0s. Specifically, an RD cannot be 0:0. 4-byte IP address:2-byte user-defined number, such as 192.168.122.15:1. The IP address ranges from 0.0.0.0 to 255.255.255.255, and the user-defined number ranges from 0 to 65535. 4-byte AS number:2-byte user-defined number, such as 65537:3. The AS number ranges from 65536 to 4294967295, and the user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. Specifically, an RD cannot be 0:0. 4-byte AS number in dotted notation:2-byte user-defined number, such as 0.0:3 or 0.1:0. The 4-byte AS number in dotted notation is in the format of x.y, where x and y are integers that range from 0 to 65535. The user-defined number also ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. Specifically, an RD cannot be 0.0:0.

Usage Guidelines

Usage Scenario

On a BGP VPLS network, you must configure an RD for a VSI after creating the VSI.

Prerequisites

The VSI-BGP view has been displayed using the pwsignal bgp command.

Configuration Impact

An RD can be modified after it is configured for a VSI.

Precautions

The RD of each VSI must be unique on a PE.
The RDs of VSIs with the same ID but residing on different PEs can be either the same or different.
