RE: Should I disable cdp on ISDN

CDP doesn't trigger a ISDN call. To verify use "debug dialer packet"

Sample output below.
2w1d: BR0 DDR: cdp, 272 bytes, outgoing uninteresting (no list matched)

Subject: Should I disable cdp on ISDN

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?
