Provider Backbone Bridge Commands

Provider Backbone Bridge Commands

The IEEE 802.1ah standard (Ref [4]) provides a means for interconnecting multiple provider bridged networks inorder to build a large scale end-to-end Layer 2 provider bridged network.

For detailed information about PBB concepts, configuration tasks, and examples, see the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Configuration Guide.

backbone-source-mac

To configure the backbone source MAC address, use the backbone-source-mac command in pbb configuration mode. To return to the default behavior, use the no form of this command.


Note


If the backbone source MAC address is not configured then one of the reserved addresses from the Chassis MAC pool is chosen automatically. To view the reserved address, use the show l2vpn pbb backbone-source-mac command.
