Configuring the ACIP

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:

Task

 

Command

Step 1

Specify the ATM interface, VPI, and headend

cable bind interface vpi ip-address

 

IP address.

 

 

 

 

Step 2

Optionally, enable proxy-ARP handling if

cable enable-proxy interface vpi

 

user-to-user communication is permitted for

 

 

each channel.

 

 

 

 

Note The Cisco IOS software automatically adds the bridge number aging-time 604800 to the configuration file.

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

Command

Enable integrated routing and bridging.

bridge irb

 

 

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.

Note For more information on the integrated routing and bridging feature, refer to the “Configuring

Transparent Bridging” chapter of the Bridging and IBM Network Configuration Guide.

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.
