Welcome to Explain Inbound BGP path selection.
In this skill, we're going to be focusing on the attributes that
are generally used to effect our return traffic
or our inbound traffic.
The first of these is going to be AS path prepending.
With AS path pretending, we're going
to be adding AS numbers to the AS path
to influence the traffic to not come in a certain path.
Therefore, causing it to come in another path.
That's the idea behind AS path pretending.
Then, we're going to look at multi-exit discriminator,
or the MED.
The MED is generally used between two neighboring
As's that have multiple paths between them.
And by default, that's actually all we can use it for.
However, MED does have a couple of features we can turn on
and it does have some caveats that
allow us to do some rather interesting things with MED.
So we'll be exploring that in great detail.
So those are going to be our two major topics for this skill.
Let's go ahead and jump in.
I'll see you in the next video.
