The extensions can be used to reduce processing requirements of refresh messages, eliminate the state synchronization latency incurred when an RSVP message is lost and, when desired, suppress the generation of refresh messages. An extension to support detection of when an RSVP neighbor resets its state is also defined. These extension present no backwards compatibility issues.
