The output from the
show bfd neighbors details
command on SwitchB verifies that BFD sessions have
been created and that EIGRP is registered for BFD support. As previously noted, SwitchA runs BFD
Version 1, therefore echo mode is running, and SwitchC runs BFD Version 0, so echo mode does not run.
The relevant command output is shown in bold.
