Release Information

Statement introduced in JUNOS Release 9.4.

Description

Configure route and next-hop properties in the event of a Bidirectional Forwarding Detection (BFD) protocol session failure event on an RSVP label-switched path (LSP). The failure event could be an existing BFD session that has gone down or a BFD session that never came up. RSVP adds back the route or next hop when the relevant BFD session comes back up.

Options

make-before-break—When a BFD session fails for an RSVP LSP, an attempt is made to signal a new LSP path before tearing down the old LSP path.

teardown—When a BFD session fails for an RSVP LSP, the associated LSP path is taken down and resignaled immediately.

teardown-timeout seconds—When you configure the make-before-break option, you can specify a time in seconds for the teardown-timeout option. At the end of the time specified, the associated RSVP LSP is automatically torn down and resignaled.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
