Dan,
Check out this link:
http://www.cisco.com/warp/public/104/dcprob.html
If I remember this lab correctly it is because of the host routes on the
ISDN interfaces. Take a look at the link, the information is very
enlightening.

Subject: CCbootcamp lab 8A.
Anyone successfully get the OSPF demand circuit working here? I have tried
everything, but I am still processing 224.0.0.5's across the BRI in both
directions.
I finally gave up & looked at the configs that CC sent, but they match mine
almost perfectly!
