Hello everyone, and welcome to Protocol Deep Dive: OSPF.
[00:00: 05.797 ] My name is Sean Wilkins and this is the
Discussing Simple OSPF Communications Blocks module.
This module takes a look at the different information
blocks that are used by OSPF to advertise destination
information in a single area network.
We begin with a section discussing the way that OSPF devices initially
communicate to determine what information needs to be exchanged.
We then move into three sections that cover the three different link state
advertisement types that are used with single area OSPF.
These include the router or type 1 LSA, the network or type 2 LSA,
and the external or type 5 LSA.
Each of these sections will have a theory and lab section that will
delve into the details specific to each one of them. So now with all this out of the way, let's get started.
