Hi,
Firstly, thanks to those who responded to my message. I have spent most
of today trying to get this working. I am now convinced this is an IOS
problem. Attached below is one of the known bugs with EIGRP authentication
listed in the Bug Navigator. Whilst the specific verion that I was using is
not listed (12.1(10)), the symptoms are the same those as below. So I'll try
some other IOS versions.
Thanks,
Nik.

Protocol (EIGRP) neighbors that are neighboring with a stub EIGRP router,
the
neighbor relationship is not formed.

with
a stub eigrp router the neighbor relationship is not formed.
Only workaround found so far is to turn off md5 encryption.
