Just out of curiosity, what does a list ip networks, or show ip network <blah> show for the netmask on that network after picking up the new OSPF routes?
If you shut OSPF off and reboot, you get: IP ROUTES Destination Prot NextHop Metric Interface 0.0.0.0/0 NetMgr 206.240.130.1 1 eth:1 127.0.0.1/H LOCAL 127.0.0.1 1 loopback 206.240.130.0/25 LOCAL 206.240.130.14 1 eth:1 206.240.130.14/H LOCAL 206.240.130.14 1 eth:1 206.240.130.127/H LOCAL 206.240.130.127 1 eth:1 Turn OSPF on (and static route redistribution on) and the third entry becomes: 206.240.130.0/23 LOCAL 206.240.130.1 1 eth:1 (Note LOCAL instead of OSPF. Bad. :) This is from memory as I don't really want to reenable static route redistribution right now...) This same thing happens on a different subnet -- a 208.6.168.0/22 and 208.6.168.0/25 route are both in the table, and it uses the /22 instead of the /25. Fortunately there are no ARCs on 208.6.168.0/25... but it's still screwy. What should probably happen is that it should probably put BOTH routes in the table, rather than trying to pick between the two... then when making routing decisions later, use the most specific. I can see cases where just throwing one of the two routes away would cause problems. (Suppose one of the routes goes down, for example.)
