Questions on RSVPTE graceful restart



Hi, 

      I have the following questions on RSVPTE graceful restart:

1. Should a restarting router change the advertised Recovery Time during a
graceful restart recovery? Suppose a restarting router advertises t0 as the
recovery time after a restart. For any reason, should it advertise a
different value for the Recovery Time while it is still in a graceful
restart recovery? How about the RecoveryPath related flags (T/R/S) bits?

2. If a restarting router is allowed to change the advertised Recovery Time
during a graceful restart recovery, how should a helper react to such a
change? For example, support the advertised Recovery Time is changed from t0
to t1, should the helper extend/shrink the period when it is helping? If so,
should the helping period start from the time when the first hello is
received (and last for t1) or from the time when the first hello with the
new value is received (and last for t1)?

3. Have the class number of Capability object and the message type of
RecoveryPath (both are defined in draft-ietf-ccamp-rsvp-restart-ext-03) been
assigned?
 
     Thanks.
