HP 12500 Series Configuration Manual page 70

NOTE:
Reservation confirmation is initiated by the receiver, which sends the Resv message with an object
•
requesting reservation confirmation.
Receiving the ResvConf message does not mean resource reservation is established. It only indicates that
•
resources are reserved on the farthest upstream node where the Resv message arrived and the resources
can be preempted.
Configuring RSVP authentication
RSVP adopts hop-by-hop authentication to prevent fake resource reservation requests from occupying
network resources.
It requires that the interfaces at the two ends of a link must share the same authentication key to exchange
RSVP messages.
To configure RSVP authentication:
To do...
Enter system view
Enter interface view of MPLS TE link
Enable RSVP authentication
NOTE:
Do not configure both FRR and RSVP authentication on the same interface.
Configuring RSVP-TE GR
The RSVP-TE GR function depends on the extended hello capability of RSVP-TE. Be sure to enable the
extended hello capability of RSVP-TE before configuring RSVP-TE GR.
To configure RSVP-TE GR on each device to act as the GR restarter or a GR helper:
To do...
Enter system view
Enter MPLS view
Enable global RSVP hello
extension
Enable MPLS RSVP-TE GR
Set the RSVP-TE GR restart timer
Set the RSVP-TE GR recovery timer
Enter interface view of MPLS TE link
Use the command...
system-view
interface interface-type
interface-number
mpls rsvp-te authentication { cipher
| plain } auth-key
Use the command...
system-view
mpls
mpls rsvp-te hello
mpls rsvp-te graceful-restart
mpls rsvp-te timer graceful-restart
restart restart-time
mpls rsvp-te timer graceful-restart
