show ip ospf "area has no authentication" even if auth is in use

[Jeremy Dubrulle]

Hi,

I've a topology as in the first attachment.

Md5 authentication is in use in area 0 and each device can ping every devices.

We can see that in the second picture with the command show ip ospf int fa0/0 on R1.

But with show ip ospf on R1, I see Area has no authentication (picture 3).

Why?

Thanks,

Hi,

Are you sure you have enable authentication for the opf area 0

Have a look at this link:-

Ok I've understood that's because I enabled auth on interfaces and not in the router conf' mode.

Thanks,
