I knew as soon as I hit send that Id messed that up... obviously it cant
use HDLC or it wouldnt work on Ethernet/tokenring/fddi etc...
cdp is a media and protocol independnt protocol that runs athe data-link
layer, sending periodic messages to a multicast address.
yes it would use hdlc for serial lines, but not for anything else.
Sorry for any oconfusion.
