Thanks Vaughan,
you were right to the point, I had some trailing spaces and since the service
encryption was ON, could not see it. But when I did "show key chain", I could
see the string within the quotes with spaces.
Other thing I observed that when
you enable md5 on eigrp on one of the neighbor only; the non-md5 neighbor forms
adj with the md5 neighbor but do not learn any routes.
thanks,
Vijay
