Host has a /64, gu= ests get other IPs in that /64, and I've got a bridge set up for the jails to connect to. auto_linklocal is turned on on both sides. tcpdump on the bridge shows well-formed neighbor solicitation requests sent= to the solicited multicast address. They're never answered and don't appear in= ndp output. net.inet6.icmp6.nd6_onlink_ns_rfc4861 doesn't make any difference. --=20 You are receiving this mail because: You are the assignee for the bug.=
