Provider Backbone Bridge Commands


This module describes the Cisco IOS XR software commands used to configure the provider backbone bridge (PBB) on Cisco ASR 9000 Series Aggregation Services Routers.

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.


backbone-source-mac {mac-address}

no backbone-source-mac {mac-address}

Syntax Description

mac address

Backbone source MAC address in hexadecimal format.


Command Defaults

None

Command Modes

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
