Chapter 32 IPv6 Support on the Cisco ASR 901 Router
How to Configure IPv6 Support on the Cisco ASR 901 Router
Associating an IPv6 Static Route with a BFDv6 Neighbor
IPv6 static routes are automatically associated with a static BFDv6 neighbor. A static neighbor is
associated with a BFDv6 neighbor if the static next-hop explicitly matches the BFDv6 neighbor.
SUMMARY STEPS
1. enable
2. configure terminal
3. ipv6 route static bfd [vrf vrf-name] interface-ype interface-number ipv6-address [unassociated]
4. ipv6 route [vrf vrf-name] ipv6-prefix/prefix-length {ipv6-address | interface-type
[interface-number ipv6-address]} [nexthop-vrf [vrf-name1 | default]] [administrative-distance]
[administrative-multicast-distance | unicast | multicast] [next-hop-address] [tag tag]
