Configuring the BFD Protocol for RSVP-TE

Configure the Bidirectional Forwarding Detection (BFD) protocol for RSVP-TE to more rapidly detect failures in a network and enable faster rerouting around the failures. You can modify the BFD timers for more or less aggressive failure detection.

When configured, BFD liveness detection is established with all BFD-enabled RSVP-TE peers associated with that RSVP-TE major interface.

Note: Before the router can use the mpls rsvp bfd-liveness-detection command, you must specify a BFD license key. To view an already configured license, use the show license bfd command.

To enable BFD (bidirectional forwarding detection) on an RSVP-TE major interface:

  1. Access the interface.
    host1(config)#interface fastEthernet 4/3
  2. Enable BFD liveness detection.
    host1(config-if)#mpls rsvp bfd-liveness-detection

The peers in an RSVP-TE adjacency use the BFD timer values to negotiate the actual transmit intervals for BFD packets.

For details on liveness detection negotiation, see Negotiation of the BFD Liveness Detection Interval in the JunosE IP Services Configuration Guide.
