Protocols And Standards; Rsvp Configuration Task List; Enabling Rsvp - HP MSR2000 Configuration Manual

A GR helper considers that a GR restarter is rebooting when it does not receive hellos or receives
erroneous hellos from the restarter in three consecutive hello intervals. When a GR restarter is rebooting,
the GR helpers perform the following tasks:
• Retain soft state information about the GR restarter.
Continue sending hello packets periodically to the GR restarter until the restart timer expires.
•
If a GR helper receives a hello message from the GR restarter before the restart timer expires, the recovery
timer is started and signaling packet exchange is triggered to restore the original soft state. Otherwise,
all RSVP soft state information and forwarding entries relevant to the neighbor are removed. When the
recovery timer expires, soft state information and forwarding entries that are not restored are removed.
