I would appreciate any insight in this issue.
I am doing dialer watch on R5 and R3. Here are the configs

The route i am watching is the loopback of R3.
When i shut R3's loopback, R5 dials fine (no problem there).
When i later do a "no shut" on R3's loopback, R5 never learns the route through
ospf. Instead it shows it as "directly connect".(see below)
r5#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
200.200.200.0/32 is subnetted, 1 subnets
O IA 200.200.200.1 [110/65] via 133.14.51.1, 00:10:55, Serial1
133.14.0.0/16 is variably subnetted, 9 subnets, 3 masks
C 133.14.243.0/24 is directly connected, Serial0.2
O 133.14.1.1/32 [110/65] via 133.14.51.1, 00:10:56, Serial1
O 133.14.6.6/32 [110/65] via 133.14.56.6, 00:10:56, Serial0.1
O 133.14.4.4/32 [110/65] via 133.14.243.4, 00:10:56, Serial0.2
C 133.14.3.3/32 is directly connected, BRI0
C 133.14.5.0/24 is directly connected, Loopback0
C 133.14.35.4/30 is directly connected, BRI0
C 133.14.56.0/24 is directly connected, Serial0.1
C 133.14.51.0/24 is directly connected, Serial1
r5#
I don't think i am doing anything wrong here. What i am thinking is that R5 thi
nks that 133.14.3.3 is directly connected and never installs the ospf route in
its routing table. The isdn circuit stays up and is never brought down until i
manually clear it. But i thought the idle-timeout is supposed to check whether
the primary link is active and bring down the isdn circuit.
Note: i have also tried to shut the serial interface on R3 and bring it back up
. I got the same result.
Thanks for your help
