I've got a 7206-VXR with an NPE-G1 and IOS 12.4(22)T connected to a 3845 IOS 12.4.(15)T and am wanting to

configure BFD (bidirectional forwarding detection) between the routers.  I'm able to configure the

correct bfd commands under the 'router eigrp 1' using CLI, but there are no 'sh bdf xxx' show commands on

the 7206 router.

On the 7206 'sh ip eigrp in detail' shows that bdf in enable on the correct interface, but there are no

other show bdf commands.

The 3845 router has BDF show commands:

VoIP-MDF-3845#sh bfd ?
  neighbors  BFD neighbors

Does the 7206 REALLY support BDF and if so are the show commands different?

I did a search using the feature navigator and did not see EIGRP support for BFD on 7200s

You are typing "sh bdf" not "sh bfd"

ENG-7206-QMOE#sh bdf ?
use sh bfd?

I mis-typed that one, but the problem is still the same:

ENG-7206-QMOE#sh bfd

You seem to be correct.  I did a search on feature navigator and it seems that it is not supported

on the 3845 router either - even though it took the commands.
