Configuring IPv6 BFD for IS-IS Processes

Configuring IPv6 BFD for IS-IS Processes

By configuring IPv6 BFD for an IS-IS process, you can set parameters for dynamic BFD sessions and enable dynamic IPv6 BFD for IS-IS on all IS-IS interfaces.


  1. Run system-view

    The system view is displayed.

  2. Run isis process-id

    The IS-IS view is displayed.

  3. Run ipv6 bfd all-interfaces enable

    IPv6 BFD is enabled in the IS-IS process to establish BFD sessions.

    When global IPv6 BFD is enabled in the IS-IS process and the neighbor IPv6 status is Up, IS-IS adopts default BFD parameters to establish BFD sessions on all the interfaces.

  4. (Optional) Run ipv6 bfd all-interfaces { min-rx-interval receive-interval | min-tx-interval transmit-interval | detect-multiplier multiplier-value | frr-binding } *

    IPv6 BFD parameters are configured for setting up BFD sessions.

    • min-rx-interval receive-interval: specifies the minimum interval at which BFD packets are received from the peer end.

    • min-tx-interval transmit-interval: specifies the minimum interval at which BFD packets are sent to the peer end.

    • detect-multiplier multiplier-value: specifies the local detection time multiplier, which determines the neighbor holdtime.

    • frr-binding: indicates that the status of the IPv6 BFD session is bound to IPv6 IS-IS Auto FRR.

  5. Run commit

    The configuration is committed.
