    Enabling BFD on an IPv6 Static Route

    You can enable BFD on an IPv6 static route using the ipv6 route command with the verify bfd-liveness-detection keyword.

    You can use the following optional keywords along with the verify bfd-liveness-detection keyword:

    • The minimum-interval keyword to specify a minimum proposed transmit interval and required receive interval for BFD control packets. The range for the value is 100–65,535 milliseconds except for ES2 4G LM, for which it is 10–65,535 milliseconds. The default value is 300 milliseconds.
    • The minimum-receive-interval keyword to specify a minimum required receive interval. The range for the value is 100–65,535 milliseconds except for ES2 4G LM, for which it is 10–65,535 milliseconds. The default value is 300 milliseconds.
    • The minimum-transmit-interval keyword to specify a minimum proposed transmit interval. The range for the value is 100–65,535 milliseconds except for ES2 4G LM, for which it is 10–65,535 milliseconds. The default value is 300 milliseconds.
    • The multiplier keyword to specify a multiplier number in the range 1–255. The default value is 3.

    You can change parameters at any time without stopping or restarting the existing session. BFD automatically adjusts to the new parameter value. However, no changes to BFD parameters take place until the values resynchronize with each BFD peer.

    To enable BFD on an IPv6 static route with:

    • Next-hop address with the same value for receive and transmit intervals.
      host1(config)#ipv6 route 3ffe::/32 2222::1 verify bfd-liveness-detection minimum-interval 500 multiplier 2
    • Next-hop address with different receive and transmit intervals.
      host1(config)#ipv6 route 3ffe::/32 2222::1 verify bfd-liveness-detection minimum-receive-interval 800 minimum-transmit-interval 400

    Use the no version to remove the IPv6 static route from the routing table, thereby removing BFD from that static route.
