CDP across ISDN Lines

Does CDP run across ISDN lines? CDP is enabled at both routers at either end of an ISDN line (did a "sh cdp int" to verity that it's enabled). However, when executing a "sh cdp nei" from either router on the ISDN line, the remote router does not show up. I need CDP to run for Campus Manager.

Thanks!

Re: CDP across ISDN Lines

Just to be sure, you are executing "sh cdp nei" when the connection is established, right?

If you are using dialer interfaces, is cdp enabled on those or only on the physical interfaces?

Can you do a "debug ppp negotiation" to see what happens when the call is established?
