What I'm saying is that neither DHCPv4 nor IPv6 RA are designed to deal with prefixes that last less than a few hours. See for example RFC 4862 Section 5.5.3 paragraph e2. (That's just an example, there are other reasons why yo-yo RAs are a bad idea.) Short-term reachability indications are sent to hosts in a reactive manner, using ICMP unreachables. If any applications are unable to do the right thing with ICMP unreachables, we should fix the applications. -- Juliusz _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
