neighbor is considered dead.

Syntax
mpls rsvp-te hello-lost times
undo mpls rsvp-te hello-lost
Default
The RSVP node considers an RSVP neighbor to be dead if no response is received after sending three
consecutive hellos.
Views
MPLS view
Default command level
2: System level
Parameters
times: Specifies the maximum number of consecutive hello losses before an RSVP neighbor is considered
dead, in the range of 3 to 10.
Usage guidelines
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, enable RSVP-TE and RSVP hello extension in MPLS view.
Examples
# Set the maximum number of consecutive hello losses allowed on a node to 5.
<Sysname> system-view
[Sysname] mpls
[Sysname-mpls] mpls rsvp-te hello-lost 5
