Hi Friend,

No Sup2+TS doesnot support OSPF. Its a layer 2 sup engine only and supports Static routing and Rip protocol.

The operative word here is "not supported" , the commands are there and they will bring up adjacencies with other ospf boxes because I tested in a lab situation . Don't know why they don't pull the commands if they are not supported in that platform . You can even get bgp to work in a lab enviroment on that platform . If you use a unsupported routing protocol and have a problem and look to cisco for support you know what they will tell you.
