could be something to do with the defaults for the IOS.
default for some IOS is clear tect, and some version IOS is encrypted.

> Hi all,

> The scenario is this :

> Three router pod in a triangular fashion connected via ethernet ports to

> 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.

> 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 ,
