Two routers are connected to each other isdn BRI. No
fancy configs at all ... just trying to see if the
adjacency gets established...
The configs are as follows:
Rtr-1>interface BRI0/0
ip address 212.1.22.161 255.255.255.240
encapsulation ppp
no logging event subif-link-status
isdn spid1 610955201101
isdn spid2 610955201201
dialer idle-timeout 900
dialer map ip 212.1.22.162 broadcast 9552021
dialer-group 1
no fair-queue
ppp multilink
hold-queue 75 in
Rtr-2>interface BRI0/0
ip address 212.1.22.162 255.255.255.240
encapsulation ppp
isdn spid1 610955202101
isdn spid2 610955202201
dialer idle-timeout 900
dialer map ip 212.1.22.161 broadcast 9552011
dialer-group 1
no fair-queue
ppp multilink
hold-queue 75 in
The output of 'sh ip ospf int bri 0/0' for each router
is as follows:
Rtr-1>sh ip ospf int bri 0/0
BRI0/0 is up, line protocol is up (spoofing)
Internet Address 212.1.22.161/28, Area 0
Process ID 1, Router ID 200.100.100.137, Network
Type POINT_TO_POINT, Cost: 1562
Transmit Delay is 1 sec, State POINT_TO_POINT,
Timer intervals configured, Hello 10, Dead 40, Wait
40, Retransmit 5
Hello due in 00:00:05
Neighbor Count is 0, Adjacent neighbor count is 0
Suppress hello for 0 neighbor(s)
Rtr-2>sh ip ospf int bri 0/0
BRI0/0 is up, line protocol is up (spoofing)
Internet Address 212.1.22.162/28, Area 0
Process ID 1, Router ID 200.100.100.73, Network Type
POINT_TO_POINT, Cost: 1562
Transmit Delay is 1 sec, State POINT_TO_POINT,
Timer intervals configured, Hello 10, Dead 40, Wait
40, Retransmit 5
Hello due in 00:00:02
Neighbor Count is 1, Adjacent neighbor count is 0
Suppress hello for 0 neighbor(s)
-----------------------------------------------------
These routers are connected to each other over BRI ..
The PPP is getting established successfully, but the
neighbour relationship over this BRI interfaces (which
are point-to-point ospf interfaces) does not form. You
can see in the output of the 'sh ip ospf int' that
only Rtr-2 finds a neighbor but Rtr-1 does not find
the neighbor.
What could be the possible cause.
