Hi all,
The scenario is this :
Three router pod in a triangular fashion connected via ethernet ports to
a switch in a common vlan.
router a
| e0
|
router b ---------switch---------------router c
e0 fa0/0
OSPF is running between ethernet interfaces in area 0. Normal OSPF
works fine and each router has entries about the other in
"sh ip ospf neighbor" output.
I was trying authentication commands. I started enabling authentication
in area 0 under router ospf config " area 0 auth mess-dig"
and in the interface e0 I gave " ip ospf mess-digest-key 1 md5 7 abc"
I gave the above commands in router b and router a - it was working
fine. they could exchange the OSPF information. When I gave the same
thing in router c - router c couldn't be seen in other routers.
I tried several times but in vain. The only difference between the
routers is router c has fastethernet and models are :
1. router b 4500
2. router a 2514
3 router c 2600
On enabling the command : debug ip ospf events on router c, I observed
Mismatch authentication keys but I used the same authentication key ,
number and the password.
Any insights would be highly appreciated.
thanks
