Enabling Concurrent Routing and Bridging

To enable concurrent routing and bridging (CRB) for all bridge groups on the router:

1. From Global Configuration mode, issue the bridge crb command.

   host1(config)#bridge crb

2. (Optional) Use the appropriate show command to verify that CRB is enabled for the bridge groups on your router.

   host1#show bridge groups details

bridge crb

• Use to enable concurrent routing and bridging (CRB) for all bridge groups configured on an E-series router.
• CRB is disabled by default.
• When CRB is enabled, the router can route a protocol among a group of interfaces in one bridge group and concurrently bridge the same protocol among a separate group of interfaces in a different bridge group.
• The command takes effect for all bridge groups on an E-series router; you cannot enable CRB for some bridge groups on the router but not for others.
• Example

  host1(config)#bridge crb

• Use the no version to disable CRB on all bridge groups and restore the default bridging capability.
• See bridge crb.
