EIGRP is a very interesting routing protocol,
and it has a lot of distance vector-like attributes,
such as it really only knows what its directly
connected neighbors told it.
It doesn't have direct knowledge about other routers beyond it's
directly connected neighbors.
But at the same time, it maintains neighborships.
So in this set of videos, what I'd like to do is chat with you
about several of the things that have
to be in line for two EIGRP speakers to become neighbors,
and what would cause that to go awry. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
and what would cause that to go awry.
And I want to do a major focus in this set of videos
on authentication, which, by the way,
is one thing that if it's not right
can cause neighborships to fail.
So we'll continue this journey in the very next video.
I'll see you there in just a moment.
