Configuring Rsvp Hello Extension; Configuring Rsvp Authentication - HP 6127xlg Configuration Manual

Step
5. Configure the retransmission
interval for reliable RSVP
message delivery.

Configuring RSVP hello extension

When RSVP hello extension is enabled on an interface, the device receives and sends hello messages
through the interface to detect the neighbor's status.
If the device receives a hello request from the neighbor, the device replies with a hello ACK message. If
the device receives no hello request from the neighbor within the interval specified by the hello interval
command, the device sends hello requests to the neighbor.
When the number of consecutive lost hellos or erroneous hellos from the neighbor reaches the maximum
(specified by the hello lost command), the device determines the neighbor is in fault. If GR is configured,
the device serves as a GR helper to help the neighbor to restart. If FRR is configured, the device performs
an FRR. For more information about FRR, see
To configure RSVP hello extension:
Step
1. Enter system view.
2. Enter RSVP view.
3. Configure the maximum
number of consecutive lost or
erroneous hellos.
4. Configure the interval for
sending hello requests.
5. Return to system view.
6. Enter interface view.
7. Enable RSVP hello extension.

Configuring RSVP authentication

RSVP adopts hop-by-hop authentication to prevent fake resource reservation requests from occupying
network resources. The interfaces at the two ends of a link must use the same authentication key.
RSVP authentication can be configured in the following views:
