<p>Methods and devices for implementing Shortest Path Bridging over a VPLS network. The method includes determining, from IS-IS PDU information received by a PE switch, whether a DF configuration for the PE switch needs to be changed and, if so, the method further includes determining whether the PE switch remains a DF for one or more B-VIDs. If the PE switch is no longer a DF for one or more B-VIDs, the method further includes removing local DF associated information for the PE switch from each PW adjacency's LDP database, and removing, from a local IS-IS database, DF associated remote LDP information. The method also includes, if the PE switch has become a DF for one or more of the B-VIDs, adding, from the IS-IS database, local DF information for the PE switch to the LDP databases, and adding, from the LDB databases, DF associated remote information for the PE switch to the IS-IS database.</p> |
