pbb binding b-vsi

Function

The pbb binding b-vsi command binds an I-VSI to a B-VSI.

The undo pbb binding b-vsi command unbinds an I-VSI from the B-VSI.

By default, an I-VSI is not bound to any B-VSI.

Format

pbb binding b-vsi vsi-name

undo pbb binding b-vsi

undo pbb binding b-vsi vsi-name

Parameters

Parameter	Description	Value
vsi-name	Specifies the name of a B-VSI.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

Usage Scenario

In PBB VPLS, an I-VSI encapsulates packets into PBB frames and is bound to an attachment circuit (AC) interface for local customer edge (CE) identification. A B-VSI processes B-MAC addresses and uses the configured peer address to determine a PW's remote PE. To bind multiple I-VSIs to a B-VSI, run the pbb binding b-vsi command. PEs or SPEs on the backbone network can identify only B-VSIs.

Prerequisites

To bind an I-VSI to a B-VSI after enabling them, perform the following configurations first:

Run the pbb service-type p2p command to configure P2P as the service type for the I-VSI.
Run the pbb i-tag command to configure an I-tag for the I-VSI.
Run the pbb backbone-source-mac command to configure a B-SMAC address for the I-VSI or B-VSI.
Run the pbb backbone-destination-mac command to configure a B-DMAC address for the I-VSI.

Configuration Impact

To bind an I-VSI to a new B-VSI, run the undo pbb binding b-vsi command to delete the existing binding, and then run the pbb binding b-vsi vsi-name command to configure the new binding.

Precautions

The pbb binding b-vsi command applies only to I-VSIs.
Two I-VSIs with the same I-tag cannot be bound to different B-VSIs. The B-DMAC address of one I-VSI must be the same as the B-SMAC address of the other I-VSI in local PBB VPLS.
Before binding I-VSI and B-VSI, ensure that I-VSI and B-VSI are enabled in the same mode.
