8-) Say Thanks to Brian Dennis (Excellent Instructor BTW) for that hint, I
learn that from one of this post
Now try to remove the Authentication part and re-apply it, reboot your
routers, etc...

Hi Victor,
this is a great hint to check white space. I did this on my two routers:
R6#s | in CISCO $
R6#s | in CISCO$
key-string CISCO
R6#
R1#s | in CISCO $
R1#s | in CISCO$
key-string CISCO
neighbor 192.10.1.254 password CISCO
R1#
Which reveals also a neigbor statement, but this is from a bgp
configurations.
So this was great help, but now tells me, i was right with withspaces.
There are none. Well i really don't know where to look. I find it also
strange, that R6 is saying it receives MD5 and R1 is not telling that.
