- This lesson is going to get into some layer two technologies.
Specifically, we'll talk about trunking,
setting up a trunk between a couple
of Cisco Catalyst switches using .1Q trunking,
we'll talk about EtherChannel,
but the big focus of this lesson
is on Spanning Tree Protocol, STP.
And yes, those are topics that we covered at the CCNA level,
but we're going to go deeper here in this lesson.
Oh, for example, we're going to see
how to configure Multiple Spanning Trees Protocol,
but let's get started in this lesson
with a quick review of .1Q trunking.
