(Optional) Configuring IPv6 BFD for a Specified Interface

(Optional) Configuring IPv6 BFD for a Specified Interface

You can configure IPv6 BFD parameters on a specified interface. The priority of IPv6 BFD parameters on an interface is higher than that of IPv6 BFD parameters in the process.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run isis ipv6 bfd enable

    IPv6 BFD is enabled on the interface to establish IPv6 BFD sessions.

    After IPv6 BFD is globally enabled in an IS-IS process, default IPv6 BFD parameters are used for establishing IPv6 BFD sessions.

  4. (Optional) Run isis ipv6 bfd { 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.

    By default, the minimum interval at which IPv6 BFD packets are sent or received is 1000, in milliseconds; the IPv6 BFD local detection multiplier is 3.


    The priority of IPv6 BFD configured on an interface is higher than that of IPv6 BFD configured for a process. That is, if BFD is also enabled on an interface, the parameters on the interface are preferentially used to establish a dynamic BFD session.

  5. Run commit

    The configuration is committed.
