mpls te bfd tunnel block

Function

The mpls te bfd tunnel block command blocks the one-arm BFD capability on a specified SR-MPLS TE tunnel interface.

The undo mpls te bfd tunnel block command enables the one-arm BFD capability.

By default, the SBFD for SR-MPLS TE tunnel and one-arm BFD for SR-MPLS TE tunnel functions are disabled.

Usage Guidelines

Usage Scenario

After the mpls te bfd tunnel enable one-arm-echo command is run in the MPLS view, one-arm BFD is enabled for all E2E SR-MPLS TE tunnels. To disable this function on a specified tunnel, run the mpls te bfd tunnel block command.

Precautions

The undo mpls te bfd tunnel enable one-arm-echo command in the tunnel interface view is different from the mpls te bfd tunnel block command:

After the undo mpls te bfd tunnel enable one-arm-echo command is run in the tunnel interface view, the tunnel interface is still capable of one-arm BFD for SR-MPLS TE tunnel if the mpls te bfd tunnel enable one-arm-echo command is run in the MPLS view.
If the mpls te bfd tunnel block command is run in the tunnel interface view, one-arm BFD for SR-MPLS TE is disabled even if the mpls te bfd tunnel enable one-arm-echo command is run in the MPLS view.
To enable one-arm BFD for SR-MPLS TE tunnel for a majority of tunnel interfaces, run the mpls te bfd tunnel block command for each tunnel interface that does not need the function and then run the mpls te bfd tunnel enable one-arm-echo command in the MPLS view.
To enable one-arm BFD for SR-MPLS TE tunnel for a small number of tunnel interfaces, run the mpls te bfd tunnel enable one-arm-echo command on each of these interfaces.
