I see. As I come to think about it, I even don't know how to enable a DHCPv6 client. In my test IPv6-only host, I keep only the following in rc.conf.local: ifconfig_vtnet0="" ifconfig_vtnet0_ipv6="inet6 accept_rtadv" ipv6_privacy="YES" > But it only does it once. rtsold is needed in case router info > changes, or your address times out. -Alan Now I understand, thank you. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
