Abstract: A method apparatus and computer readable medium for preforming SPB-PIM multicast interactions is presented. A Backbone Edge Bridge (BEB) in a Shortest Path Bridging (SPB) network discovers a multicast stream originating within a Protocol-Independent Multicast (PIM) network. The BEB sends multicast information to a Rendezvous Point (RP) in the PIM network. The BEB advertises a multicast stream learned from the RP into the SPB network. The BEB receives an update that includes a receiver interest in said multicast stream and initiates PIM join procedures for permitting the receiver to receive the multicast stream.

Abstract: A method, apparatus and computer program product for providing the use of an external metric as the primary tie-breaker in ISIS route selections is presented. A set of routes are identified that are to be advertised by the router as external routes within a network. The routes are advertised by the router using a Type Length Variable (TLV), wherein the TLV contains metric information to be used as a first tiebreaker when selecting routes. The network is running an Intermediate System To Intermediate System (ISIS) protocol. The TLV includes a 32-bit or a 64-bit administrative tag sub-TLV, the TLV comprising TLV#135, TLV#235, TLV#236, and TLV#237.

Abstract: A method, apparatus and computer program product for providing a best route selection rule is presented. A determination is made at a first edge router, whether a second edge router in a network advertises a first BMAC address and at least one other BMAC address When the second edge router advertises only a first BMAC address, then the first BMAC address is used in a routing table for a Layer 3 (L3) next hop for a route. When the second edge router advertises more than one BMAC address, at least one other BMAC address is used in the routing table for said L3 next hop for the route.
