Cisco Systems ACIP-SM(=) Configure Protocols for Routing or Bridging, Interface bvi bridge-group

Configuring the ACIP

To create a bridge-group virtual interface, perform the following tasks in interface configuration mode:

Task		Command
Step 1 Enable a bridge-group virtual interface.		interface bvi bridge-group
Step 2	Specify the IP address for the interface.	ip address ip-address mask
Step 3	Disable the sending of redirect messages.	no ip redirects
Step 4	Optionally, enable fast-switching on the	ip route-cache same-interface
	interface.

Note For more information on bridge-group virtual interfaces, refer to the “Configuring

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

Configure Protocols for Routing or Bridging

When integrated routing and bridging is enabled, the default route/bridge behavior in a bridge group is to bridge all packets.

You can then explicitly configure the bridge group to route a particular protocol, so that routable packets of this protocol are routed, while non-routable packets of this protocol or packets for protocols for which the bridge group is not explicitly configured to route will be bridged.

To configure specific protocols to be routed in a bridge group, perform the following task in global configuration mode:

Task	Command
Specify the IP protocol to be routed in a bridge group.	bridge bridge-grouproute ip

When you intend to bridge and route a given protocol in the same bridge group, you must configure the network-layer attributes of the protocol on the bridge-group virtual interface. Do not configure protocol attributes on the bridged interfaces. No bridging attributes can be configured on the bridge-group virtual interface.

Although it is generally the case that all bridged segments belonging to a bridge group are represented as a single segment or network to the routing protocol, there are situations where several individual networks coexist within the same bridged segment. To make it possible for the routed domain to learn about the other networks behind the bridge-group virtual interface, configure a secondary address on the bridge-group virtual interface to add the corresponding network to the routing process.

Note For more information on the protocols to be routed in a bridge group, refer to the “Configuring Transparent Bridging” chapter of the Bridging and IBM Network Configuration Guide.
