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.
ENG-7206-QMOE#sh ip eigrp interfaces detail
IP-EIGRP interfaces for process 1
Xmit Queue Mean Pacing Time Multicast Pending
Interface Peers Un/Reliable SRTT Un/Reliable Flow Timer Routes
Gi0/1.10 1 0/0 1 0/2 50 0
Hello interval is 5 sec
Next xmit serial <none>
Un/reliable mcasts: 0/338172 Un/reliable ucasts: 224946/977
Mcast exceptions: 6 CR packets: 6 ACKs suppressed: 13
Retransmissions sent: 82 Out-of-sequence rcvd: 5
Authentication mode is not set
BFD is enabled
Use multicast
ENG-7206-QMOE#sh bdf ?
% Unrecognized command
ENG-7206-QMOE#sh bdf
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
^
% Invalid input detected at '^' marker.
ENG-7206-QMOE#sh ?

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.

Is CISCO 7206 VXR, version 12.2(33)SRE3 have BGP support for BFD? I tried on GNS3. Did bfd config on interface, but once i configure fall-over bfd under BGP then router s/w got crashed. Also suggest supportive IOS for this purpose
