Configure Cable Parameters
To assign the ATM interface on the ACIP to a cable headend and specify the cable headend IP
address, perform the following tasks beginning in global configuration mode:

Configure the Integrated Routing and Bridging Feature
After you have set up the interfaces in the router, you can enable integrated routing and bridging.
To enable integrated routing and bridging, perform the following task in global configuration mode:
Task
Enable integrated routing and bridging.
Use the show interfaces irb privileged EXEC command to display the protocols that a given bridged
interface can route to the other routed interface when the packet is routable, and to display the
protocols that a given bridged interface bridges.

Configure the Bridge-Group Virtual Interface
The bridge-group virtual interface resides in the router. It acts like a normal routed interface that does
not support bridging, but represents the entire corresponding bridge group to routed interfaces within
the router. The bridge-group virtual interface is assigned the number of the bridge group that it
represents. The bridge-group virtual interface number is the link between the bridge-group virtual
interface and its bridge group. Because the bridge-group virtual interface is a virtual routed interface,
it has all the network layer attributes, such as a network address and the ability to perform filtering.
Only one bridge-group virtual interface is supported for each bridge group.
When you enable routing for a given protocol on the bridge-group virtual interface, packets coming
from a routed interface but destined for a host in a bridged domain are routed to the bridge-group
virtual interface, and are forwarded to the corresponding bridged interface. All traffic routed to the
bridge-group virtual interface is forwarded to the corresponding bridge group as bridged traffic. All
routable traffic received on a bridged interface is routed to other routed interfaces as if it is coming
directly from the bridge-group virtual interface.
Specify the ATM interface, VPI, and headend
IP address.
Optionally, enable proxy-ARP handling if
user-to-user communication is permitted for
each channel.
The Cisco IOS software automatically adds the bridge number aging-time 604800 to the
