A virtual link in OSPF, hopefully,
if we've designed the network correctly,
we'll never need to use one.
However, in a pinch, it's a great Band-Aid
that we might have to implement.
So in this set of videos for IPv4's OSPF, OSPF version 2.
We are first of all going to introduce
the concept of virtual links.
I'd like to give you a lab hands on that you can practice
implementing and verifying one.
And then we'll follow up with a couple of videos
and a couple of labs regarding troubleshooting WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
and a couple of labs regarding troubleshooting
OSPF networks that have virtual links in them.
So without further ado, I'll see you in the very video.
