Use Of 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)

摘要

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.
