rrpp snooping all-vsi

Function

The rrpp snooping all-vsi command associates a sub-interface with the VSI that all the other sub-interfaces connected to the same primary interface are bound to.

The undo rrpp snooping all-vsi command cancels the association.

By default, a sub-interface is not associated with the VSI that all the other sub-interfaces connected to the same primary interface are bound to.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730S-H, and S6730-H support this command.

Usage Guidelines

Usage Scenario

In the scenario of RRPP and VPLS association, when the RRPP ring fails, the RRPP snooping-enabled sub-interface clears the forwarding entries on the associated VSI and the remote VPLS device, and relearns the entries. In this way, downstream traffic can be forwarded through a normal path.

You can run the rrpp snooping all-vsi command on the RRPP snooping-enabled sub-interface to associate the sub-interface with the VSI that all the other sub-interfaces connected to the same primary interface are bound to. The sub-interface clears all the forwarding entries of associated VSIs when the preceding fault occurs.

Prerequisites

RRPP snooping has been enabled using the rrpp snooping enable command.

Precautions

You must run the l2 binding vsi vsi-name command to bind other interfaces connected to the same primary interface to the VSI before associating the VSI using the rrpp snooping all-vsi command on the current sub-interface.
You can run the undo rrpp snooping all-vsi command to cancel all the associations between the current sub-interface and the VSIs bound to other interfaces connected to the same primary interface.
You do not need to enable RRPP snooping on other sub-interfaces connected to the same primary interface.

Example

# Associate the sub-interface with VSIs that all the other sub-interfaces connected to the same primary interface are bound to.
