: Maximum number of consecutive hello losses before an RSVP neighbor is
considered dead.
Description
Use the
mpls rsvp-te hello-lost
command to configure the maximum number of
consecutive hello losses before an RSVP neighbor is considered dead.
Use the
undo mpls rsvp-te hello-lost
command to restore the default.
By default, the RSVP node considers an RSVP neighbor is dead if no response is
received after sending three consecutive hellos.
An RSVP node detects whether its RSVP neighbor is still alive by sending hellos
regularly. If no response is received after the number of consecutive hellos reaches the
specified limit, the RSVP node considers its RSVP neighbor as dead. The failure is
handled the same as a link layer communication failure.
Before you can configure this command, enable RSVP-TE.

considered dead to five.
