Whoops, didn't read this very carefully. Chua is right, your using 2
different methods here. As far as the demand circuit goes, try taking the
dialer watch out of the picture and just running it as a demand circuit,
with the additions I stated before.

~It sound like you are using dialer watch and demand circuit
~together, I am not sure will this give you the desire result.

~Subject: OSPF Demand Circuit Problems
~
~
~Hello,
~
~I am having difficulty with an OSPF demand circuit running
~over an async
~interface.
~
~The line comes up as desired with a dialer watch-group,
~however, when the
~line goes down again, OSPF shows the LSAs updating and re-dials. This
~continues every 120 seconds (idle-timeout) forever.
~
~As far as I can see, the links are configured properly (ip ospf
~demand-circuit, ip ospf network point-to-point).
~
~There are no other relevant factors (not redistributions or
~other unstable
~links).
~
~
~My network is configured roughly in a square,
~
~(This is the Hello Computers Security Lab 2 core network, for
~those of you
~with access. No other routers are configured right now so as
~to eliminate
~the possibility of interaction).
~
~Router 1 and 5 share an ethernet LAN that is area 0.
~Router 5 is connected to router 2 via frame.
~Router 2 is connected to router 4 via frame.
~Router 4 is connected to router 5 via the DDR async.
~
~All frame/DDR networks are area 1.
~
~ [R5] --/DDR/-- [R4]

~
~I have reviewed, investigated, and attempted all the
~applicable fixes listed
~at the following URL:
~
~http://www.cisco.com/warp/public/104/dcprob.html
~
~Attached is the complete R4 and R5 configuration along with a up/down
~snapshot of the "show ip ospf database" information.
