Hello everyone, and welcome to Protocol Deep Dive: OSPF.
My name is Sean Wilkins, and this is the Introducing Multi-Area OSPF module.
With this module we take a look at multi-area OSPF.
We will begin with a section defining what multi-area OSPF is and how it can be
used to optimize the way that routing information is shared.
Next we move on to a section on the different OSPF device types,
specifically talking about the different roles that devices take on
when configured in a multi-area OSPF network.
We then have a section covering the different types of
OSPF area that can be implemented,
including how they could be used to further limit the
size of the link state database.
And finally we have a section on the different link
state advertisements that are used,
specifically when implementing multi-area OSPF over single area OSPF. So now with all of this out of the way, let's get started.
