Hello, everyone, and welcome to Protocol Deep Dive: OSPF.
My name is Sean Wilkins and this is the Forming Basic OSPF Relationships module.
This module begins a discussion on OSPF neighborships.
In this module we will begin with a section discussing OSPF neighborships.
specifically covering the different requirements
that must be met for them to form.
We will then move into the lab and show neighborships forming and
how not meeting these requirements affects them.
We then move into a section on OSPF network types and how
they alter the behavior of OSPF devices.
Next we will move into a section discussing the different neighbor
states and what happens during each of them.
We then move into the lab and track a neighborship as it
forms and show the different log states.
And in our final section we cover the OSPF packet,
specifically reviewing each one of the major fields that are
used in each type and what they are used for.
For this section we will move into the lab during the discussion and show
what each one of these packets looks like on a live capture. So now with all this out of the way, let's get started.
