摘要： Embodiments generally relate to enabling encapsulation in networks. In one embodiment, a method includes receiving a message from an edge configuration device, wherein the message contains shortest path bridging (SPB) configuration information. The method also includes performing provider backbone bridge (MAC-in-MAC) encapsulation in response to receiving the message.

摘要： A method, apparatus and computer program product for providing multi-homing techniques for SPB networks is presented. A set of UNI nodes that receive multicast packets are determined based on Backbone Media Access Control-Destination Address (BMAC-DA)/I-Tag Service Identifier (I-SID) of received multicast packets for multicast packets within a transport network. A separate Egress Port Mask is determined for each Backbone-Virtual Local Area Network (B-VLAN) of the transport network, wherein the Egress Port Mask is determined such that only one UNI node of the set of UNI nodes forwards said multicast packets. A set of UNI copies of said multicast packets are filtered out by applying the Egress Port Mask, wherein copies that are not in the Egress Port Mask are dropped. Copies of multicast packets that are not dropped are sent out.

摘要： 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.

摘要： Embodiments generally relate to enabling configuration in networks. In one embodiment, a method includes receiving a message from an edge configuration device, wherein the message contains shortest path bridging (SPB) configuration information. The method also includes performing an intermediate system-to-intermediate system (IS-IS) configuration in response to receiving the message.
