Re: Understanding IPv6

Hmmmm... Well, organizing things into sections is generally a good way
to tackle it.

As for LAN operations, most of those magical things revolve around the
basic premise that there are NO BROADCASTS! Which is cool in many
ways. It also (if your old like me (grin)) brings back many of the
concepts from the old IPX networking days. Back in the day, you set up
a Novell server, you powered up your workstations and relative magic
happened.

They discovered who they were (duh, it was their MAC). They discovered
where they were (network broadcasts) and discovered what servers were
around (server advertisement broadcasts).

Now, we've evolved things a little bit, but the general concepts are
still there. We're just a touch more polite with the multicast and
anycast idead floating around. Neighbor Discover, Router Adverisements,
Router Solicitations, things like that are the evolution. If you aren't
old like me, then much of it will seem foreign.

It's all about the magic of the network though.

As for the tunneling types... make yourself a list of all the types.
Go find the RFC's for them, and pay particular attention to what order
they came about. You'll start to see an evolution pattern that may
actually make them make some more sense. You are correct, there's a
number of different things to work with.

And if the lab doesn't spell it out, you can probably do whatever method
you like, in which case I'd pick the easiest! (grin)

HTH,
