OSPF "bad hello packet"

[James A. Crippen]

I'm getting "bad hello packet from 10.1.1.23 received: bad netmask
255.255.255.0" even though there's really nothing wrong with this netmask
(I'm using 10.1.1.0/24 and 10.2.2.0/24 for some testing).

Is there any reason why ospf thinks this is a bad netmask?  Should I just
ignore it?

Thanks!
