Abstract
Coordinating gateways for multi-destination traffic across a TRILL fabric and a VXLAN/IP fabric with a plurality of TRILL IS-IS TLVs and a plurality of Layer 3 IS-IS TLVs is provided herein. The plurality of TRILL IS-IS TLVs and the plurality of Layer 3 IS-IS TLVs effectuate: grafting an IP multicast share tree with a plurality of TRILL distribution trees at only one of a plurality of gateways in a network interworking a TRILL fabric and a VXLAN/IP fabric; ensuring that multicast traffic traversing from the plurality of TRILL distribution trees is not looped back to the TRILL fabric through the VXLAN/IP fabric; restoring connectivity among a plurality of VXLAN/IP fabric partitions through the TRILL fabric if the VXLAN/IP fabric is partitioned; and restoring connectivity among a plurality of TRILL fabric partitions through the VXLAN/IP fabric if the TRILL fabric is partitioned.
