Hello, and welcome to troubleshooting BGP.
In this troubleshooting scale, what we're going to be doing
is going through a series of troubleshooting tickets
and trying to solve problems on our equipment.
Now, these tickets are not going to be end user type
tickets, of course, because they're network-related issues,
they're going to be more like maybe tickets you
would get from tier 1 or maybe a junior admin,
that sort of thing.
It's going to be things like BGP neighborships aren't working
or we're not getting this route on this router
that we're supposed to have in a certain way
or something along those lines.
So we're going to go through some very common BGP issues,
take a look at how to troubleshoot them.
Now keep in mind as we jump in.
A lot of times, console messages and log messages
are going to give us a lot of information as far
as troubleshooting these issues.
And we're going to not use those, at least not at first.
We may revert back to looking at them at some point,
but the fact of the matter is sometimes
for some of these issues it would just put the problem
right in our face, and there wouldn't really
be too much to troubleshoot.
And normally, that might be a good thing.
However, since this is an educational experience,
we want to go through and look at other things
that we can see that would show us the same problem.
So just keep that in mind that normally when
you're troubleshooting, one of the first things to do
is check your log files and check any console messages,
again, assuming you happen to be logged into the equipment
while the problems are occurring.
So all of that said, we're going to jump into these tickets.
We're going to go through them one by one,
and we're going to solve the issues
that we're seeing in BGP.
So this should be a lot of fun.
I'll see you in the first ticket.
