<p>A method is implemented in a multiprotocol label swapping (MPLS) edge switch (PE) for interworking the 802.1aq control plane with an Ethernet Virtual Private Network (EVPN) Border Gateway Protocol (BGP) control plane. The method and system elect designated forwarders (DFs) for a given Backbone- Virtual Local Area Network Identifier (B- VID) in a local Provider Backbone Bridged Network (PBBN) and thereby determine which PE uniquely transfers specific I- Component Source Identifier (I- SID) and Media Access Control (MAC) information for the B- VID from an Intermediate System- Intermediate System (IS- IS) database into a BGP database and transfers I- SID and MAC information in the BGP database into the IS IS database of the PE.</p> |
