Configuring Multiprotocol BGP Extensions for IP Multicast

Multiprotocol BGP Configuration Task List

Multiprotocol BGP Network Advertisement Examples

The following examples show how to use an address family to inject a network number and mask into the unicast database and the multicast database:

router bgp 100 address-family ipv4 unicast

network 10.0.0.0 mask 255.0.0.0

router bgp 100 address-family ipv4 multicast

network 10.0.0.0 mask 255.0.0.0

Multiprotocol BGP Route Map Examples

The following example shows how to use an address family to configure BGP so that any unicast and multicast routes from neighbor 10.1.1.1 are accepted if they match access list 1:

router bgp 50000

neighbor 10.1.1.1 remote-as 1 address-family ipv4 unicast

neighbor 10.1.1.1 route-map filter-some-multicast in

router bgp 50000

neighbor 10.1.1.1 remote-as 1 address-family ipv4 multicast

neighbor 10.1.1.1 route-map filter-some-multicast in neighbor 10.1.1.1 activate

route-map filter-some-multicast match ip address 1

Multiprotocol BGP Route Redistribute Examples

The following example shows how to use an address family to redistribute DVMRP routes that match access list 1 into the multicast database and the unicast database of the local router:

router bgp 50000 address-family ipv4 unicast

redistribute dvmrp route-map dvmrp-into-mbgp

router bgp 50000 address-family ipv4 multicast

redistribute dvmrp route-map dvmrp-into-mbgp

route-map dvmrp-into-mbgp match ip address 1
