Proposal: Rework ipv6 rtsol initialization in rc.d Why: on multihomed or transient (e.g. laptops) connections, ipv6 autoconfiguration can be slow, causing ipv6 initialization delays while waiting for unsolicited router advertisements What: add devd.conf entries, create /etc/rc.d/rtsol script (ala dhclient script), modify network.subr, update man 5 rtsol Discussion point: There is a comment in network.subr, and in man 5 rtsol about multihomed connections not being appropriate for rtsol I read through RFC 2461 and 2462, and while it does list multihomed issues in appendix A of RFC 2461, it does not have any "MUST NOT" or "SHOULD NOT" language around router solicitations with respect to multihomed ipv6 systems. (Someone, please correct me if I am wrong here, or if there is some other RFC that applies) The multihomed issue is more around IPv6 autoconfiguration in general, not specific to soliciting for a router. Since FreeBSD already allows for IPv6 autoconfiguration on multihomed ipv6 systems (just without calling rtsol on multiple interfaces), I would think that this is really a non-issue for rtsol. Comments ? Please let me know if I am way off base here. I will gladly submit a patch for review if no one has any objections to multihomed ipv6 rtsol. --Thanks! ---_Dave Horn Non quia difficilia sunt non audemus, sed quia non audemus, difficilia sunt.
