C. Router CLI Commands, Codes, and Designations

Bridge Commands

Bridge commands are used to enable or disable simultaneous bridging and routing, configuration of bridge groups and their attributes, and apply or remove bridge groups from an interface or sub-interface.

Minimum Access Level: Administrator

Command Mode: config

A user can enable or disable simultaneous bridging and routing and configure attributes associated with a bridging group. Bridge group 1 is created by default with a priority of 32768 and configured as a learning bridge utilizing the IEEE 802.1 spanning tree protocol.

Simultaneous routing and bridging is disabled by default. Once concurrent routing/ bridging is enabled, you must configure an explicit bridge route for any protocol to be routed on interfaces in a bridge group.

Example: bridge crb 1 route ip

crb – Enable or disable concurrent routing and bridging on the device.

bridge-group– Bridge group 1 is created by default. If a bridge-group is specified, one of the following attributes must be specified:

acquire – Configure a learning bridge that is capable of dynamically learning new stations. This argument is configured by default on all bridge groups. The no bridge command is not accepted for this argument.

aging-time– Specifies the length of time that an unused dynamic entry is maintained in the bridge table. The no bridge command resets the aging-time to the default value.

aging-time– Valid range is 10–1,000,000 seconds. The default is 300.

protocol – Specify a spanning tree protocol.

span-tree-protocol– Valid spanning tree protocol for IEEE 802.1 protocol is ieee.

priority – Specify the priority ranking for this bridge. The higher the number, the less likely this bridge will be selected as the spanning tree root.

span-tree-priority– Valid priority values when spanning tree protocol is IEEE.802.1 are: 0–65535. The default is 32768.

route – Specify a protocol to be routed in this bridge group when concurrent routing and bridging are enabled.

route-protocol– Valid routing protocol is IP.
