Sorry for bothering you again, but I don't think I've ever seen any
responses to my question...could you please answer them? Or, if I
miss something foundamental, please kindly say so.

I have a couple of questions on the draft:
1. what should a host do when it receives an RA with the preference
field being set to 10 (i.e. reserved)?
- ignore the entire RA.
- accept the RA, but consider the preference value as another value?
if so, high/medium/low?
- other option?
2. if the preference value for a router changes, does/should it
affect existing destination cache entries? For example, consider
the following scenario:
- a host H receives an RA from a router R1 with the medium
preference.
- H sends a packet to an off-link destination D. H uses R as the
next hop, and records H in the destination cache.
- a host A then receives an RA from another router R2 with the high
preference.
now, what should happen on the destination cache for D in H?
Should it be removed once, prompting H to do next hop determination
again (and to choose the more preferred router R2). Or, should H
just keep the old cache and its next hop until it becomes
unreachable?
