 Given that it is 9-CURRENT and the box has 1 NIC (fxp0), add the
 following line to rc.conf:

 ifconfig_fxp0_ipv6="accept_rtadv"

 ifconfig_fxp0_ipv6="inet6 2001:db8:1::1/64"

 ifconfig_fxp0_ipv6="inet6 2001:db8:1::1/64 accept_rtadv"

jh> A router kind of box, what should it look like?

 Given that the box has 2 NICs (fxp0 and fxp1), add the following lines
 to rc.conf:

 ipv6_gateway_enable="YES"
 ifconfig_fxp0_ipv6="inet6 2001:db8:1::1/64"
 ifconfig_fxp1_ipv6="inet6 2001:db8:2::1/64"

 And, no ifconfig_IF_ipv6 line means no IPv6 configuration for the IF.

 After my changes committed last September, the existence of
 ifconfig_IF_ipv6 is used as a flag for whether IPv6 is enable or not
 on that interface.
