Hello and welcome to scaling iBGP neighborships.
In this skill, we're really going
to be exploring how to prevent having
to have a full mesh of iBGP neighborships
because full meshes don't scale very well.
Of course, the fundamental problem is in BGP,
we have a rule of split horizon.
Which means that if I receive iBGP updates from one iBGP
peer, I cannot send them out to another.
Therefore, the only way to get all the updates through
would be to have a full mesh.
But of course, we can't do that in most environments.
So we do have two major technologies
that we can use to alleviate this.
We have confederations.
And we have route reflectors.
And these can be used either separately or together.
So what we're going to be doing in this skill
is building a BGP network from the ground up,
using a combination of confederations and route
reflectors.
So in our first video here, we're
going to be jumping in and putting together an entire game
plan, as far as what we're going to be building.
So we have a lot of things we're going to be covering.
It's going to be a lot of fun building this network
from the ground up.
So I'll see you in the next video
to put our game plan together.
