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. Thanks, JINMEI, Tatuya Communication Platform Lab. Corporate R&D Center, Toshiba Corp. [EMAIL PROTECTED]
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? JINMEI, Tatuya Communication Platform Lab. Corporate R&D Center, Toshiba Corp.
