Command Reference Guide Global Configuration Mode Command Set
When IRB is enabled and a BVI is configured, IP network configuration is removed for all bridged
interfaces. IP traffic destined for the BVI address is delivered to the local IP stack for routing (if routing is
enabled) or management. If no BVI is configured, the behavior is the same as if IRB is not enabled.
When IRB is not enabled, a BVI cannot be created. Bridged interfaces retain their IP configuration, and IP
traffic destined for those interfaces is delivered to the local IP stack.
