Whether you are running an OSPF demand circuit or not is not important.
CDP, by default, will not bring up (or keep up, for that matter) your
ISDN link unless you specifically include it in your Dialer List/Watch
configuration.

as a reader this is the most complete reply.
as I understand it, OPSF demand circuit is the only time where you would
explicity disable cdp (interface only) in order to prevent an isdn
circuit
from coming UP unecessarily.

What techology are you refering to ? It really is technology specific
backup interface => no need
static route => make sure you didn't define CDP as interesting traffic
in
the dialer-list (there is no need to turn it off)
ospf demand-circuit => filter it out or turn it off
dialer-watch=> no need i believe..not sure though..
so which one is it are you refering to ?

On page 144 CCIE Practical Studies: Security, it said
cdp triggers the ISDN call and therefore should be
disabled if it isn't needed.
Is that true? SHould I always disable cdp when
configure DDR on ISDN?
