Chris is correct on this....just one note add on CDP is ....I believe that CDP
is disabled on interfaces that are configured for frame-relay (by default).
So, you will need to go in and enable it.

ODR only gets enabled on the hub and you have to make sure that CDP is
specifically enabled and running between the interfaces connecting the
hub and spoke.

ODR does work , I promise :)

- Using c2500-is-l.122-15.T17.bin
- Both R1 and R2 give the same error messages
- no odr routes found
- have tried classful addresses too
- Have search the Cisco website
- Have searched Groupstudy archive. There was a similar thread
in March. Someone referred to a link but it is broken.

Any ideas please?
