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.
