I have a dual-homed OI workstation with the 2nd NIC on a non-routeable
private network too, and I have IPv6-specific routing issues every time
the workstation is rebooted.  My issues are (I think) coming because of
OI's in.ndpd, the IPv6 Neighbor Discovery protocol daemon.

Your issues are potentially easier, though.

1) are you running in.routed?
2) are you using nwam or statically-configured?
3) do you have anything in /etc/defaultrouter?

What happens if you do

 	sudo route -p delete -inet -dst default -gateway 203.6.241.1 -iface rge0

Does that work?  Does it change your current "netstat -rn" output?

Does it survive a reboot?
