WARNING:

Executing show cdp neighbors detail may crash your Cisco at Mae-EAST.  I
noticed this earlier today while I was browsing, but believed I had some
sort of strange interaction with my rev of IOS until this happened to
someone else running a completely different code stream.

There is apparently a device there spewing broken cdp information.  The
Cisco engineer working on this case hasn't heard of this problem before,
but if I gather anymore useful information I'll certainly pass it along.

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.
