However I've not closely followed the most recent version of FreeBSD IPv6 code, but the use of the routing table in ip6_input in the original KAME implementation had nothing to do with the strong host model. It was just for faster determination of whether an incoming packet is destined to *any* of host's IPv6 addresses (on any interface, which may or may not be identical to the receiving interface). --- JINMEI, Tatuya Internet Systems Consortium, Inc. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
