Unfortunate. When I startup radvd on a PC when its eth0 is physically down (no link at the PHY), it terminates at startup: jharan-linux2:/home/jeff/dev/ip_v6_port # /usr/sbin/radvd -d 1 -m stderr -C /home/jeff/dev/ip_v6_port/radvd.conf [Jan 15 06:30:13] radvd: version 0.9 started [Jan 15 06:30:13] radvd: no linklocal address configured for eth0 [Jan 15 06:30:13] radvd: error parsing or activating the config file: /home/jeff/dev/ip_v6_port/radvd.conf jharan-linux2:/home/jeff/dev/ip_v6_port # If I start radvd when the link is up, it starts up fine, but then if the link goes down I get error messages: jharan-linux2:/home/jeff/dev/ip_v6_port # /usr/sbin/radvd -d 1 -m stderr -C /home/jeff/dev/ip_v6_port/radvd.conf [Jan 15 06:31:41] radvd: version 0.9 started [Jan 15 06:31:58] radvd: resetting ipv6-allrouters membership on eth0 [Jan 15 06:31:58] radvd: sendmsg: Invalid argument [Jan 15 06:32:04] radvd: resetting ipv6-allrouters membership on eth0 [Jan 15 06:32:04] radvd: sendmsg: Invalid argument [Jan 15 06:32:07] radvd: resetting ipv6-allrouters membership on eth0 [Jan 15 06:32:07] radvd: sendmsg: Invalid argument jharan-linux2:/home/jeff/dev/ip_v6_port # It seems to me that this would be problematic for a linux based router if it happened to attempt to reboot and then start radvd when the link was down. Is this the way its supposed to work? Is there a way of defeating this so that the link local address stays put regardless of physical link state?
