So let's finish up this module by taking a look at the
different things that were discussed.
We began with a section defining what multi-area OSPF is and how it is used
to optimize the way that routing information is shared.
Next we moved into 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 moved into a section covering the different
types of area that can be implemented,
including how they can be used to further limit the
size of the link state database.
And finally we had a section on the different link
state advertisements that are used,
specifically when implementing multi-area OSPF over single area OSPF.
I hope that this information was useful and will help you further your understanding of OSPF.
