Configuring for Network Management Applications
CDP
and “E” are
not
neighbors because the intervening CDP-disabled switch “D”
does not forward CDP packets; i.e. is not transparent to CDP traffic. (For the
same reason, switch “E” does not have any CDP neighbors.)

"A", "1", "2", and "3" are CDP neighbors.
"A" and "B" are CDP neighbors.
"B" and "C" are CDP neighbors.
Because "D" is CDP-capable, but has
disabled CDP, it is not a CDP neighbor
to either "B" or "E".
