On FreeBSD 6.3-RELEASE, it does work ok. >How-To-Repeat: Basic IPv6 config : machine1: sysctl -w net.inet6.ip6.forwarding=1 ifconfig bge0 inet6 2001:a:b:c::2/64 route -n add -inet6 default 2001:a:b:c::fffa machine2: sysctl -w net.inet6.ip6.forwarding=1 ifconfig bge0 inet6 2001:a:b:c::3/64 route -n add -inet6 default 2001:a:b:c::fffa Both addresses are pingable, and when I use either of them on other machines as gateway, they route fine. So now carp : machine1: ifconfig carp1 create ifconfig carp1 vhid 1 pass mekmitasdigoat ifconfig carp1 inet6 2001:a:b:c::1/64 machine2: ifconfig carp1 create ifconfig carp1 vhid 1 advskew 100 pass mekmitasdigoat ifconfig carp1 inet6 2001:a:b:c::1/64 carp goes succesfully to master on one machine, and to backup on another. However..... i can't ping the virtual address 2001:a:b:c::1 from either machine1 or machine2. Nor can other PC's in the network ping it or use it as a gateway. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
