Ivan,
That means your igp is unstable. What if the area is not totally stubby? Check
the basic igp stuff, then you will learn alot more than turning the area into t
otally stubby. (Because I have encountered what you have now)

Hi,
Yes, its correct.
I've changed the area 10 where the dialer interface is in into a totally stubby
area and that solves the issues.
Thanks

It might be because you are redistributing a distance vector protocol into OSPF
, which generates an LSA over the link at each update period.

Hi,
I've configured AUX back to back to simulate DDR across ISDN.
I've also configure it as a IP OSPF Demand Circuit.
However OSPF continues to bring up the link.
The link is under an OSPF area 10.
The debug dialer shows the reason for the link being bring up:
-------------------------------------------------------------
Mar 4 03:59:57.249 EST: As1 DDR: rotor dialout [priority]
Mar 4 03:59:57.253 EST: As1 DDR: Dialing cause ip (s=110.99.25.2, d=224.0.0.5)
Mar 4 03:59:57.257 EST: As1 DDR: Attempting to dial 1234
Mar 4 03:59:57.257 EST: CHAT1: Attempting async line dialer script
Mar 4 03:59:57.261 EST: CHAT1: Dialing using Modem script: isdn & System scrip
t
: none

Mar 4 03:59:58.201 EST: CHAT1: Chat script isdn finished, status = Success
MU-R2#
----------------------------------------------------------------
Since the hello is suppressed over the point to point dialer link,
I'm not sure what OSPF is sending out on the all router multicast address acros
s the dialer interface. The other reason i can think of is when a topology chan
ge that trigger the link but there is none.
Appreciate if anyone can advice on this.
Thanks
Ivan Lim
