Problem is, with OSPF, routed doesn't cut it any longer. Routed uses RIP;
you're using OSPF as your routing protocol. Since the UN*X boxes now only
have their "default route" as the "correct" place to go for your users' IP
addresses, you either (1) need to have the Cisco redistribute the OSPF
routes into RIP, (2) need to have the PM's do both RIP and OSPF, or (3) just
live with it. Since you won't install OSPF on all the unix boxes, they need
to get their routing info from somewhere, or else the router will ICMP
Redirect them away.
