A long time ago, we learned as one of our early principles
of network design and also network control
is that we want to take large networks
and break them up into smaller chunks,
not just to reduce broadcast domains, but also
so that we can force traffic through routers
and we can have access controllers on those routers.
Now, we have come a long way since those early ideas
because we now have the need in most networks
to take traffic within a VLAN and microsegment
that or control the traffic between one port
here and other port here in the same logical network. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
here and other port here in the same logical network.
There are several techniques that we
could use to implement that including TrustSec,
but one way that we can control traffic within a VLAN,
to control what ports are allowed
to talk to what other ports, is by using
the concept of a private VLAN, and that's
what this set of videos is all about.
So I look forward to seeing you in the next one
as we take a look at the bigger picture of what
is a private VLAN, what are its parts,
and then proceed through configuring and verifying it
together.
I'll see you in the next video.
