Welcome to Troubleshooting IS-IS.
This skill is going to be formatted just a little bit
differently from how we normally do a skill in that we're
going to take what would normally be a perfectly
working IS-IS environment.
In fact, it's the same environment
that we've been working with in all of the previous IS-IS
skills.
And we're going to look at that with some problems introduced
into the topology.
Then we're going to work through a series of trouble tickets
to fix these problems in our environment.
Now, these tickets are going to be formatted
sort of like they're coming from junior engineers or maybe tier
one tech support, not really coming
from the users themselves.
So they'll be a little bit more specific than just something's
not working.
They'll be things like maybe a neighborships down,
or we're supposed to have a certain route
on a certain router, and we don't have it.
So that's how the tickets will be formatted.
So as we go through here, hopefully, we'll
get a lot of hands-on skills with troubleshooting IS-IS
as we try to get our environment back up
and running and working as it's supposed to.
So again, this should be a lot of fun.
Let's go ahead and jump in.
I'll see you in the next video.
