Example: Enabling IPv6 Multicast Routing

The following is a sample configuration of IPv6 Multicast feature on the Cisco ASR 901 router.

Current configuration : 64 bytes

interface Vlan100 no ip address

ipv6 address 100::1/64

end

Example: Configuring IPv6 SSM Mapping

The following is a sample configuration of IPv6 SSM mapping on the Cisco ASR 901 router.

Building configuration...

Current configuration : 111 bytes

interface Vlan110 asr901-multicast source no ip address

ipv6 address 110::1/64 ipv6 ospf 100 area 0

end
