Pat- I may be hitting this issue way bellow the knees, but have you ever
thought of running an IBGP session. You could create a channel or path
connection between the two OSPF networks for fail-over, load balance, &
geographical routing (if your current connection involves is BGP peering @
the ISP). This could be done before the PIX's, not to allow port 179 TCP
openings in the firewalls...
