Hello, and welcome to Exploring IPv6 Tunneling Options.
In this skill, we're going to be going over
different ways of tunneling IPv6 over an IPv4-only core.
Now, we're going to start off actually
by talking about dual stack, which
is simply running both IPv4 and IPv6 at the same time.
This is critical to understand because it's actually
a fundamental principle of tunneling because our tunnel
endpoints are going to have to be dual stack.
Now, the other routers in the transport network
don't have to be, but the tunnel endpoints do.
So we need to understand how that functions.
Then we'll move on and talk about some
of our manual tunnel options, GRE and IPv6 6in4 tunnels.
Then we'll start talking about some automatic tunneling
options.
So we'll move on to talking about 6to4.
And then we'll talk about 6RD, which
is used to address a drawback that we have with 6to4 tunnels.
Finally, we'll wrap up with talking about how
we transport IPv6 over MPLS.
Now, that's not directly tunneling,
but it is encapsulating the IPv6,
and it is still carrying it over an IPv4-only core.
So it does sort of belong in the same category.
So as you can hear, we have a whole lot of fun stuff
to cover.
So join me as we jump in and start
talking about our IPv6 tunneling options.
