The reason the DDR is staying up 24 hours is the eigrp hello packeats are causing the diealer to dial. The address that eigrp multicasts its hello packets is 224.0.0.10. Your dialer list does not preclude eigrp hello multicast address.
Your dialer list should go something like this : First use extended access-list to blobk the eigro multicast address: access-list 100 deny ip any host 224.0.0.9 --- prevents eigrp multicast packets access-list 100 permit ip any any or access-list 100 deny eigrp any any access-list 100 permit ip any any your new dialer list will read like this: dialer-list 1 protocol ip list 100 ----- point to access list 100 also I recommend you disable cdp on both sides od the isdn connection by using the command: no cdp enable Also since you are using PPP, you may want to implement chap authentication since you are running no authentication.
