Guys,

Been playing with eigrp authentication. i have 3
routers on the same ethernet segment with all exactly
the same key chains etc, all are ntp synced and i am
only able to get the neighbours up between 2 routers.

I think that perhaps there is something strange going
on so i got to 2 routers connected serially, the
configure the same configs on bith routers bu they
don't come up. below is the relevant configs for the
ethernet routers. can anyone see where i have stuffed
them up? r6 & r3 are neighbours, nothing will play
with r1
