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.

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.
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.
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:
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.
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
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.
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.
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.
and bridging are enabled.
route-protocol – Valid routing protocol is IP.
