Why on EARTH?!? would _ANYONE_ run CDP at a MAE or any other exchange point?
Especially given the congestion, and other problems at the MAE's, why run
a protocol to discover other Cisco's you have to explicitly configure peering
sessions with anyway? If someone can explain a reason not to turn off CDP
at an exchange point, I'm all ears.
