8.3 Configuring VPLS Convergence (UPE Directly

Connected to the NPE)

between the NPEs and set the precedence for the mVRRP to determine the master NPE and the

backup NPE. The mVRRP packets are transmitted and forwarded through the mPW and the

mVSI between the UPE and the NPE.

The service VSI and service PW also need to be set up between the UPE and the NPE to transmit

and forward service packets from an access network.

VPLS convergence is deployed on the UPE and the NPEs. After mVRRP and the mVSI are

correctly configured, the service data of users can be sent to the master NPE. When the master

NPE or the link between the UPE and the master NPE fails, the backup NPE automatically

becomes the master NPE and the service data of users are sent to the new master NPE.

In addition, different from the service VSI, the mVSI is used to transmit and intercept the

ARP packets; therefore, you cannot shut down the mVSI.
