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.
