So in conclusion, keep in mind that troubleshooting MPLS
is much like troubleshooting anything else.
It's useful to have a structured methodology
that we're going to use to approach each problem.
Notice that the first thing we did on all of our tickets
was to verify or validate the ticket.
Make sure it's accurate because, first, somebody else may have
already fixed the ticket, and we sure
don't want to waste our time and the company's time doing
research and troubleshooting something that's
not even a problem anymore.
Or it's also a possibility that the ticket was
reported wrong to begin with.
Maybe the junior admin who did the initial troubleshooting
misunderstood something or missed something.
So we always want to start with that validation.
Also, keep in mind something we didn't do in this skill
because we wanted to take sort of a more roundabout approach
to each ticket, but something that's also useful--
always look at log files.
Look at your network management software.
Maybe we even go into something like Wireshark
and do some packet captures.
Those are all incredibly useful tools for our troubleshooting
process.
And we always want to make sure that we use
all the tools in our toolbox.
But all of that said, that does conclude this skill.
I hope that you pulled something out of this
that can help you in your everyday careers
while you're troubleshooting MPLS.
So congratulations on completing Troubleshooting MPLS.
I hope this has been informative for you,
