Hello everyone, I need help. My box(Machine1) by default will perform IPv6 stateless autoconfiguration and I need to change this autoconfigured address to static manually without restarting. Here are the steps I follow but I sure I missed something cause I was unsuccessful of doing it. 1. I disabled sysctl knob to stop receiving rtadv # sysctl -w net.inet6.ip6.accept_rtadv=0 2. I then removed the autoconfigured ipv6 address from the interface # ifconfig em0 inet6 2001:db8:1234:abcd:20c:27ff:fe3d:63dd delete 3. I removed the default ipv6 route since I will replace with another route # route delete -inet6 default 4. I then added the autoconfigured ipv6 address back to the interface to make it static # ifconfig em0 inet6 2001:db8:1234:abcd:20c:27ff:fe3d:63dd prefixlen 64 up 5. I added the new default ipv6 route # route add -inet6 default 2001:db8:1234:abcd::1 At this point I pinged 2001:db8:1234:abcd:20c:27ff:fe3d:63dd from another IPv6 box (Machine2) with IPv6 address of the same prefix (2001:db8:1234:abcd:215:d3ff:fe4f:acaf) but with no success. But if I ping6 from Machine2 to my router 2001:db8:1234:abcd::1 I am successfull. I tried to check IPv6 route information from Machine1 thru netstat -rnf inet6 but have not found this entry: 2001:db8:1234:abcd::/64 link#1 UC em0 I hope someone could shed light on how to put this route into my ipv6 routing table. Is this a bug in FreeBSD not to automatically add a routing prefix after changing from IPv6 stateless autoconfiguration to static IPv6 address ? Thanks, Romskie
