Some more miscellaneous comments/questions on the ND draft ( I originally sent this email over the weekend but it bounced )
1. If a 6lowpan contains multiple 6LBRs, how should a 6LR reply to a router solicitation from a host? Should it send multiple router advertisement messages in response ? 2. If a context with valid lifetime = 0 is received from another 6LR or 6LBR, does a 6LR have to delete the context only after completing the dissemination of the context? How long should this time be ( considering that sleeping devices can sleep for very long times.. ). In general updating of context information seems unreliable in presence of sleeping nodes 3. If a host completes DaD on a global address where the IID is derived from its link layer address, can it safely assume that a link local address derived from the same IID is also unique ? That is, can it automatically configure a LL address based on that IID without going through the registration process again for that address ? 4. Add a new failure status code for the NA ( "neighbor cache at capacity" ). This will be used if the 6LR has a full neighbor table and cannot allow another host to register through it. The host can then attempt registration through another 6LR -Regards, Joseph _______________________________________________ 6lowpan mailing list [email protected] https://www.ietf.org/mailman/listinfo/6lowpan
