The situation and symptom are the following: 1. The box has two NICs. One has an address 2001:0db8:1::1/64 (NIC A), and another has 2001:0db8:2::1/64 (NIC B). These addresses are assigned manually ($ipv6_ifconfig in rc.conf). 2. RA is periodically sent to the network 2001:0db8:1::1/64 (NIC A) by a router on the subnet. The RA includes a source link-layer address option only. When setting net.inet6.ip6.accept_rtadv=1 in this configuration, I expected the box assigns an autoconf IPv6 address (prefix 2001:0db8:1::/64 + EUI64) to NIC A and an default route based on source link-layer address in the RA packet. Actually, these two were done as expected. However, after addresses are assigned, routes for NIC B disappeared from the routing table. More specifically, a cloning route "2001:0db8:2::1/64 -> link#2" was removed for some reason. Is this an expected behavior? IIRC, 7.0R does not remove the route and I think it is strange. It works fine if a box has a single NIC, though. -- | Hiroki SATO ----Security_Multipart(Mon_Jan_12_04_20_14_2009_954)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEABECAAYFAklqRm4ACgkQTyzT2CeTzy0vYgCgy2+jwbltC4hR4Gqs1o0LFy0L 2wcAoJkmPjB2wf/VEJedj4FrfyAySoUv =5+wj -----END PGP SIGNATURE----- ----Security_Multipart(Mon_Jan_12_04_20_14_2009_954)----
