(Optional) Preventing an Interface from Dynamically Establishing an IPv6 BFD Session

(Optional) Preventing an Interface from Dynamically Establishing an IPv6 BFD Session

You can disable certain IS-IS interfaces from dynamically establishing IPv6 BFD sessions.


After the ipv6 bfd all-interfaces enable command is used for an IS-IS process on a P2P network, all IS-IS interfaces whose neighbors are Up establish dynamic BFD sessions; all IS-IS interfaces whose neighbors are Up on a broadcast network establish BFD sessions between DISs and non-DISs. If you do not expect certain IS-IS interfaces to establish dynamic BFD sessions, you can disable these interfaces from dynamically establishing BFD sessions. Do as follows to disable the specified interface from dynamically establishing BFD sessions:


  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 block

    The interface is prevented from dynamically establishing a BFD session.

  4. Run commit

    The configuration is committed.
