3Com MSR 50 Mpls rsvp-te hello-lost, # Enable Rsvp hello extension on interface Ethernet 1/0

View MPLS view, interface view

Parameter None

Description Use the mpls rsvp-te hello command to enable RSVP hello extension.

Use the undo mpls rsvp-te hello command to disable RSVP hello extension.

By default, RSVP hello extension is disabled.

RSVP-TE uses the hello mechanism to detect whether an RSVP neighbor is still alive.

Before you can enable RSVP hello extension in interface view, enable RSVP-TE in interface view and RSVP hello extension in MPLS view.

Example # Enable RSVP hello extension in MPLS view.

Parameter times: Maximum number of consecutive hello losses before an RSVP neighbor is considered dead, in the range 3 to 10.

Description Use the mpls rsvp-tehello-lostcommand to configure the maximum number of consecutive hello losses before an RSVP neighbor is considered dead.

Use the undo mpls rsvp-tehello-lostcommand 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.
