Cisco Systems 78-11741-02 manual Verifying Multiprotocol BGP Configuration and Operation, Options

Configuring Multiprotocol BGP Extensions for IP Multicast

Multiprotocol BGP Configuration Task List

To configure an aggregate address for multiprotocol BGP, use the following commands beginning in global configuration mode:

	Command	Purpose
Step 1
	Router(config)# router bgp autonomous-system	Configures a BGP routing process and places the
		router in router configuration mode.
Step 2
	Router(config-router)#address-family ipv4 multicast	Specifies the IP Version 4 address family type and
		places the router in address family configuration
		mode.
Step 3
	Router(config-router-af)# aggregate-addressaddress	Configures an aggregate address with various
	mask [as-set][summary-only][suppress-map map-name]	options.
	[advertise-map map-name][attribute-map map-name]

Note Aggregate addresses that are defined in router configuration mode using the aggregate-addressas-setcommand are injected into the unicast database by default. To enter an aggregate address in another database, such as the multicast database, the aggregate address must be defined in address family configuration mode using the aggregate-addressas-setcommand, as shown.

See the “Aggregate Multiprotocol BGP Address Examples” section for aggregate multiprotocol BGP address configuration examples.

Verifying Multiprotocol BGP Configuration and Operation

To verify multiprotocol BGP configuration and operation, perform the following steps:

Step 1 Enter the show ip bgp ipv4 multicast EXEC command to display information related to the multicast database:

Router# show ip bgp ipv4 multicast
