A SYSTEM AND METHOD OF DEMULTIPLEXING PROVIDER BACKBONE BRIDGING TRAFFIC ENGINEERING INSTANCES

摘要

The present disclosure generally relates to a technique of operating a Backbone Edge Bridge (EEB) having two different incoming Ethernet Switched Paths (ESPs) that share the same Backbone Source MAC Address (B-SA) and the same Backbone VLAN Identifier (B-VID) but have different Backbone Destination MAC Addresses (B-DAs). A method implementation of this technique comprises receiving Continuity Check Messages (CCMs) that arrive on the two different ESPs and distinguishing between the CCMs that arrive on the different ESPs based on different B-DAs.
