Method and apparatus for resolving conflicting unicast advertisements in a transport network

摘要

A method, apparatus and computer program product for resolving conflicting unicast advertisements in transport network is presented. A particular Backbone Virtual Local Area Network (BVLAN) as a first BVLAN (BVLAN1) on a first network device in a transport network. The first network device receives a first message from a second network device advertising a first Backbone Media Access Channel (BMAC) on a first BVLAN (BMAC1,BVLAN1). The first network device receives a second message from a third network device advertising the (BMAC1,BVLAN1). The (BMAC1,BVLAN1) is assigned to the device of the second network device and the third network device having a lower Identifier (ID) value, wherein the ID value comprises one of the group comprising an Intermediate System to Intermediate System (ISIS) system ID and a Shortest Path Bridging (SPB) bridge ID.

主权项

1. A computer-implemented method comprising:
designating a particular Backbone Virtual Local Area Network (BVLAN) as a first BVLAN on a first network device in a transport network; receiving, at said first network device, a first message from a second network device advertising a first Backbone Media Access Channel (BMAC) on said first BVLAN; receiving, at said first network device, a second message from a third network device advertising said first BMAC on said first BVLAN; detecting a conflict due to said first BMAC on said first BVLAN being advertised by said second network device and said third network device; recognizing that said particular BVLAN is said first BVLAN; and assigning said first BMAC on said first BVLAN to the device of said second network device and said third network device having a lower Identifier (ID) value on said first BVLAN.
