I'm taking a stab in the dark, but I think CDP sends traffic about every 90
seconds... Do a SHOW CDP Interface and see how often it is sending packets.
If that is the case turn CDP off. If nothing else activate the improbability
drive.

Subject: Legacy DDR won't keep quiet [7:20854]
Howdy there folks, question for you. Studying for the BCRAN, I have a lab
with two 1602R's with BRI modules. I am simulating a FR connection with BRI
configured for backup in legacy dialer-string mode.
The backup works fine; ie. I pull the FR cable and the backup comes up, I
send interesting traffic and the BRI dials and routes the packet.
Problem is, even when there is no interesting traffic (even when I put an
access list on it with 'deny any') the BRI still dials periodically. As far
as I can tell it's about 90 seconds between.
At first I thought it was RIP. But I disabled RIP and it's still doing it!
Here's the config on the spoke router (note Hitchhiker's Guide reference =)

Why would this thing dial for no reason??? Let me know your thoughts.
BTW congrats to the recent CCIE Written folks (there were a couple recently,
no?)
Thx, -Sean.
