#446 Bug: IPv6 default route is not set, although ipv6_defaultrouter is set

[O. Hartmann]

When setting IPv6 enabled and assign a static IPv6 (in our case an ULA) to the LAN interface as well as a default IPv6 gateway, then there is no default route set!
Checking /etc/rc.conf indicates, that

ipv6_defaultrouter="fd00:xxxx:xxx::1"

is already set and correct, but checking routing via

netstat -Warn

reveals that only for IPv4 the default reoute is set properly, IPv6 is missing.

fd01:17a::10 link#1 UHS 0 16384 lo0
fe80::%em0/64 link#1 U 0 1500 em0

And /etc/rc.conf shows the correct defaultrouter entry for IPv6 (I rebooted the box especially to check, setting the default route for IPv6 via <route -6="" default="" fd01:17a::10=""> results in a correct setting and so a working IPv6 system.</route>
