(Optional) Configuring Dynamic BFD for IPv4 Static Routes

(Optional) Configuring Dynamic BFD for IPv4 Static Routes

Pre-configuration Tasks

Before configuring dynamic BFD for IPv4 static routes, complete the following task:

  • Configure link layer parameters and IP addresses for interfaces to ensure that the link layer protocol on the interfaces is Up.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run bfd

    BFD is enabled globally.

  3. Run quit

    Return to the system view.

  4. (Optional) Run ip route-static default-bfd [ min-rx-interval min-rx-interval ] [ min-tx-interval min-tx-interval ] [ detect-multiplier multiplier ]

    Global BFD parameters are configured for static routes.

    By default, the values of min-rx-interval, min-tx-interval, and detect-multiplier are 1000 ms, 1000 ms, and 3 respectively.

  5. Run ip route-static bfd [ interface-type interface-number ] nexthop-address [ local-address address ] [ min-rx-interval min-rx-interval | min-tx-interval min-tx-interval | detect-multiplier multiplier ] *

    BFD parameters are configured for an IPv4 static route.

    NOTE:

    If interface-type interface-number is not specified, local-address address must be specified.

    If none of min-rx-interval, min-tx-interval, and detect-multiplier is specified, the global default values of BFD parameters are used.

  6. Run ip route-static ip-address { mask | mask-length } { nexthop-address | interface-type interface-number [ nexthop-address ] } [ preference preference | tag tag ] * bfd enable [ description text ]

    A public network static IPv4 route is bound to a BFD session.

    NOTE:

    When the type and number of the outbound interface of a static route are specified, and the VPN instance name is specified, a static route searches the routing table of the VPN instance for an outbound interface according to nexthop-address. Run the ip route-static vpn-instance vpn-source-name destination-address { mask | mask-length } interface-type interface-number [ nexthop-address ] [ preference preference | tag tag ] * bfd enable [ description text ] command to bind a dynamic BFD session to static routes.

  7. Run commit

    The configuration is committed.

Verifying the Configuration

Run the following command to verify the configuration.

  • Run the display bfd session { all | discriminator discr-value } [ verbose ] command to check information about the BFD session.
