Abstract: A method, apparatus and computer program product for performing multicast Backbone Media Access Channel (BMAC) header transformations is presented. A packet having a header is received at a network node. The header is modified to produce a packet having a modified header by replacing an original value inside the header with a less granular value. The packet having a modified header is forwarded into a transport network.

Abstract: A method, apparatus and computer program product for providing Virtual Routing and Forwarding (VRF) and gateway Media Access Controller (MAC) distribution is presented. At least one subnet associated with a Layer 2 Virtual Switching Network (L2VSN) is provided on a network device. A message is propagated to a distributed Datapath. Network devices install the message as a routable MAC address on the L2VSN for the Layer 3 Virtual Switching Network/Virtual Routing and Forwarding (L3VSN/VRF) associated with the message. Edge devices route packets on the L2VSN addressed to the gateway MAC address.

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 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 using Backbone Virtual Local Area Network (BVLAN) as Virtual Routing and Forwarding (VRF) Identifier and shared Backbone Media Access Control (BMAC) tables to implement a Shortest Path Bridging (SPB) Layer 3 (L3) Virtual Services Network (VSN) is presented. For routed traffic, a Layer 3 (L3) Virtual Services Network (VSN) is associated with a unique Virtual Local Area Network Identifier (VLAN_ID) value in a first Shortest Path Bridging (SPB) network for routed traffic. The routed traffic comprises traffic sent over an SPB network interface, traffic received from an SPB interface, or traffic forwarded from a first SPB Network interface to a second SPB Network interface.

Abstract: A method and apparatus for automated mirroring is presented. A network device running as a Fabric Attach (FA) server configured to mirror traffic to a Remote Switch Port Analyzer (RSPAN) Virtual Local Area Network (VLAN), issues an FA Type Length Value (TLV) on its uplink to the FA server. The TLV includes a request to associate said RSPAN VLAN with a Service Identifier (I-SID) used to carry mirror traffic in a network. The network device sends the mirrored traffic on the RSPAN VLAN on its uplink to the FA server. The network device signals the I-SID into the network, and detects receive interest in the I-SID. The network device delivers the mirrored traffic to devices that expressed a receive interest in the mirrored traffic.

Abstract: Multicast link trace Connectivity Fault Management (CFM) is implemented in an Ethernet network by causing nodes on the network which perform Reverse Path Forwarding Check (RPFC) based on packet Source Address (SA) to not update the packet SA when updating the content of the CFM message. Alternatively multicast CFM is implemented by causing nodes on the network to update the packet SA when the content of the CFM message is updated, but cause a secondary RPFC process to be implemented by a control process in connection with processing the CFM message. The secondary RPFC process is based on a combination of source and content contained in the payload of the CFM message.
