neighbor pairs are as follows: A/1, A/2, A/3, A/B, B/C. Note that "C" 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".
