mpls rsvp-te hello-lost
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 configuring this command, be sure to enable RSVP-TE and enable RSVP hello extension in MPLS
view.
Related commands: mpls rsvp-te timer hello.

mpls rsvp-te keep-multiplier
Description
Use the mpls rsvp-te keep-multiplier command to configure the keep multiplier for the PSB and RSB.
Use the undo mpls rsvp-te keep-multiplier command to restore default.
The default keep multiplier is 3.
The following equation determines the timeout time of the state stored in PSB and RSB:
Expired_Time = (keep-multiplier + 0.5) × 1.5 × refresh-time
refresh-time is the refresh interval for reservation state set by the mpls rsvp-te timer refresh command.
