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
