pbb i-tag

Function

The pbb i-tag command configures an I-tag in PBB VPLS.

The undo pbb i-tag command deletes an I-tag in PBB VPLS.

By default, no I-tag is configured in PBB-VPLS.

Usage Guidelines

Usage Scenario

After enabling an I-VSI, perform the following configurations for the I-VSI to take effect:

Run the pbb service-type p2p command to configure the PBB VPLS service type.
Run the pbb i-tag command to configure the I-tag.
Run the pbb backbone-source-mac command to configure the B-SMAC address.
Run the pbb backbone-destination-mac command to configure the B-DMAC address.
An I-tag is a field in the MAC header of a public network packet and is defined in 802.1ah. An I-tag uniquely identifies an I-VSI. To configure an I-tag, run the pbb i-tag command.

Prerequisites

An I-VSI has been enabled using the pbb i-vsi enable command.

Configuration Impact

If the pbb i-tag command is run more than once, the latest configuration overrides the previous one.

After an I-VSI is bound to a B-VSI, you must remove the binding before changing the value of an I-tag or running the undo pbb i-tag command.

Precautions

In a VPLS domain, a pair of I-VSIs must have the same I-tag that is unique on the entire network.

Example

# Configure an I-tag of 2000 for an I-VSI named vsi_1.
