mpls rsvp-te bfd (Interface view) (Switch)

Function

The mpls rsvp-te bfd enable command enables the BFD for RSVP capability on an interface.

The undo mpls rsvp-te bfd enable command disables the BFD for RSVP capability on an interface.

The mpls rsvp-te bfd block command blocks the BFD for RSVP capability on an interface of a CR-LSP.

The undo mpls rsvp-te bfd block command enables the BFD for RSVP capability.

By default, the BFD for RSVP capability on an interface is disabled.

Format

mpls rsvp-te bfd { enable | block }

undo mpls rsvp-te bfd { enable | block }

Parameters

Usage Guidelines

Usage Scenario

The mpls rsvp-te bfd enable command and the mpls rsvp-te bfd block command are covering each other. When using these commands, note the following:

If the undo mpls rsvp-te bfd enable command is run to disable BFD for RSVP on an RSVP interface, the interface can still obtain the BFD for RSVP capability after you configure the mpls rsvp-te bfd all-interfaces enable command in the MPLS view.

If the mpls rsvp-te bfd block command is run on an interface, the interface cannot obtain the BFD for RSVP capability even if the mpls rsvp-te bfd all-interfaces enable command is run in the MPLS view.

To enable the BFD for RSVP capability on a majority of interfaces, you can run the mpls rsvp-te bfd block command on a minority of interfaces that do not need to be enabled with BFD for RSVP. Then, you can run the mpls rsvp-te bfd all-interfaces enable command in the MPLS view to enable the BFD for RSVP capability for the desired majority.
To enable BFD for RSVP capability on a few interfaces, you can run the mpls rsvp-te bfd enable command on these specific interfaces. In addition, you can run the undo mpls rsvp-te bfd enable command or the mpls rsvp-te bfd block command to disable BFD for RSVP on these interfaces.

Prerequisites

BFD has been enabled globally.

RSVP-TE has been enabled on interfaces and the node.
