I spent some time thinking about Section 5.1.3 of draft-gont-6man-slaac-renum-01. This the part where the host deals with stale prefixes. I'm interested in the host part for two reasons: - Solving the issue at the CPE requires persistent storage of network state, which may be hard to require from all devices. - It may take quite a long time before all CPEs are replaced. So for any host it is worth dealing with the problem locally instead of relying on the network. I find the following issues in draft-gont-6man-slaac-renum-01: - In the notes it says "The aforementioned processing assumes that while network configuration information might be split into multiple RAs, PIOs will be spread among *at most* two RAs." I think it is bad to deploy something on hosts that would force all routers to comply with this. - The draft proposes many changes to router behavior in particular increasing the frequency of RA multicasts. One problem is that hosts will only benefit from those changes when new CPEs are deployed. The draft doesn't describe what will happen in networks with unmodified CPEs - Increased multicast rates may have a negative effect on battery lifetime. - The algorithm has a tight coupling between modifying the preferred and valid lifetimes of addresses. In most cases, accidentially marking an address as deprecated has little effect on connectivity. Deleting an addresses by setting the valid time to zero immediately disrupts all communication that uses the address. What is worse, these changes to the valid time are not necessary do deal with the problem at hand: flash renumbering situations. With respect to valid lifetimes, if two hosts are communicating locally using global addresses, is it worth breaking that communication just because the router ceases to send RAs for the prefix (i.e. well before the lifetime of the prefix or the onlink status expires) So I was looking at a change to host processing of RAs such that: - The host will quickly (on a human time scale) stop using the old prefix - Any mistakes because the algorithm gets confused are relatively benign - No changes to routers are required for the algorithm to work, though some currently allowed router behavior may lead to sub-optimal results. The basic concept that I came up with is the following: - I assume that for each addresses that is configured using SLAAC the host already maintains an associated default router to deal with poor man's multihoming setups. - Add to each address a timetamp value that records when the last time a PIO (with A bit set) was seen that covers the prefix (last_time_seen). For each RA that is received, if the RA contains any PIO with the A bit set, processes those PIOs and update the last_time_seen value for addresses covered. Update the default router as well. For each PIO with A bit set and preferred lifetime non-zero, collect the label values (based on the policy table in RFC 6724 "Default Address Selection") in a set. After processing all PIOs in the RA go over all addresses: - Skip any addresses that have a different default router - Skip any addresses that have a label not in the set that resulted from processing the PIOs - Skip any addresses that have a last_seen_value that was less than 60 seconds ago - If the address has a preferred lifetime of more than 60 seconds, reduce the lifetime to 60 seconds. I picked 60 seconds because it is a value that works well on a human time scale. At the same time, if a router announces PIOs in multiple RAs then they should be sent within 60 seconds to see no change in host behavior. (I guess that for battery lifetime it is best to send all multicasts together). If a router would spread RAs out over a longer period, hosts will follow the RAs causing load to be distributed over multiple prefixes in a predictable fashion. In simple CPE situations, this will cause old addresses to be deprecated 60 seconds after the CPE first announces the new prefix (most of the time). In rare cases, where the CPE quickly reboots just after sending an RA, it may take one extra round of RAs (at the moment 10 minutes). In cases where a router spreads PIOs over multiple RAs, if those are sent within 60 seconds and there is no packet loss, all addresses remain preferred. If the RAs are spread over a longer interval or if there is packet loss, one or more addresses may get deprecated. To deal with accidentally deprecated addresses, the algorithm makes sure that an address gets deprecated only if there is a new address with the same label. The biggest risk here is that a ULA may accidentally cause a global address to be deprecated.
