Configuring Static BFD for RIP

Procedure

1. Enable BFD globally.
   1. Run system-view

      The system view is displayed.

   2. Run bfd

      BFD is enabled globally.

   3. Run quit

      Return to the system view.

2. Configure Static BFD.
   1. Run bfd session-name bind peer-ip ip-address [ interface interface-type interface-number ] [ source-ip ip-address ]

      BFD binding is created.

      If a peer IP address and a local interface are specified, BFD detects only a single-hop link, that is, a route with the interface specified in the bfd command as the outbound interface and with the peer IP address specified in the peer-ip command as the next-hop address.

   2. Set discriminators.

      • Run discriminator local discr-value

        The local discriminator is set.

      • Run discriminator remote discr-value

        The remote discriminator is set.

      The local discriminator must be the remote discriminator of the device on the other end; otherwise, a BFD session cannot be established. The local and remote discriminators cannot be modified after being configured.

      local discr-value set on the local device is the same as that of remote discr-value set on the remote device.remote discr-value set on the local device is the same as that of local discr-value set on the remote device.

   3. Run quit

      Return to the system view.

3. Enable static BFD on an interface.
   1. Run interface interface-type interface-number

      The view of the specified interface is displayed.

   2. On an Ethernet interface, run undo portswitch

      The interface is switched to Layer 3 mode.

      By default, an Ethernet interface works in Layer 2 mode.

      The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.

      If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

   3. Run rip bfd static

      Static BFD is enabled on the interface.

   4. Run quit

      Return to the system view.

4. Run commit

   The configuration is committed.
