# bridge crb

#### Syntax

[ no ] bridge crb

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Enables concurrent routing and bridging (CRB) for all bridge groups configured on the router except those bridge groups configured as VPLS instances. 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 on the router. The no version disables CRB on all bridge groups and restores the default bridging capability.

The command takes effect for all bridge groups on the router not configured as VPLS instances; you cannot enable CRB for some bridge groups but not for others.

#### Mode

Global Configuration
