Configuring the RSVP refreshing mechanism
To enhance reliability of RSVP message transmission, the Message_ID extension mechanism is used
to acknowledge RSVP messages. The Message_ID extension mechanism is also referred to as the
reliability mechanism throughout this document.
After you enable RSVP message acknowledgement on an interface, you may enable retransmission.
To use summary refresh (Srefresh), you must use the Message_ID extension. Only states advertised
using MESSAGE_ID included Path and Resv messages can be refreshed using summary refreshes.
