When we have to send our traffic over other people's networks,
including public networks, we want to keep all that traffic
safe and secure and bundled up.
And the way we do that is with some encryption
and hashing algorithms and using this suite of protocols
called IPSec.
That's certainly one way of doing it.
Now, in a previous set of videos,
we took a look at the fundamentals of IPSec.
And in this set of videos, we're going
to take a look at putting those pieces together
with the good old fashioned site-to-site tunnel using
IPSec with Cisco IOS routers.
And this journey continues in the next video, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And this journey continues in the next video,
and I'll see you there in just a moment.
