Hello, this is my isdn config:
interface BRI0/0
ip address 133.1.35.5 255.255.255.252
encapsulation ppp
ip ospf demand-circuit
dialer map ip 133.1.35.6 name rack01r3 broadcast 62194683
dialer load-threshold 128 either
dialer-group 1

no peer neighbor-route
no cdp enable
ppp authentication chap callin

This is the result of show dialer:

very stable,and no /32 mask ,as you can see
but when I use "debug ip ospf monitor", it shows continuous message like this every 60 seconds:
>09:35:39: OSPF: Syncing Routing table with OSPF Database
>09:35:39: OSPF: Completed Syncing and runtime is 8 msec

>09:36:39: OSPF: Syncing Routing table with OSPF Database

>
>09:37:39: OSPF: Syncing Routing table with OSPF Database
>09:37:39: OSPF: Completed Syncing and runtime is 8 msec
This is my version:
Version 12.1(5)T9
Now I am curious if there is a bug in this version? I referenced a doc in cco:
http://www.cisco.com/en/US/tech/tk826/tk365/technologies_tech_note09186a008009481b.shtml
But I didn't find any one of these reasons it lists .
