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.
