Purpose
Enables IRB. Allows bridging of traffic.
Configures the BVI by assigning the number of the
corresponding bridge group to the BVI. Each bridge
group can have only one corresponding BVI.
Configures IP addresses on routed interfaces.
Exits the interface configuration mode.
Enables a BVI to accept and route routable packets
received from its corresponding bridge group.
Enter this command for each protocol that you want
the BVI to route from its corresponding bridge
group to other routed interfaces.
Returns to the privileged EXEC mode.
(Optional) Saves your configuration changes to
NVRAM.
