Hello. Welcome back. Cisco Certified Design Associate or Joy 11. Last 11.1. I mean, instructor.
In the previous video we talked about, I s i s from this video, we will begin to introduce a Wes P s.
Here's the pre assessment question. A network engineer requires that on O S p f a S p r master only flood external always stays
only within its own area. What SPF area type should be configured a backbone area? Be totally study area seeing also stop the area

Here's the topic We will discuss
West PF version two areas as a never gross
The initial flooding and the database maintenance off our essays can burn in the rodders of CPO. West PF uses areas to reduce this effects on area is a logical grouping of the writers and links that divides the network.
Brothers iShares link state information with only the writers in their areas
using the apology with the multiple areas to provide to the following and benefits the second imitation of the network. It reduces the number off us, have petey calculations.
The segmentation of the network reduces the amount of our I say flooding

Well, the SPF area high to the apology from another era. Each area is a sign of a 32 bit Diane ticker number area zero or 0.0 dot zero as a reserve that for the backbone era, every all SPF network, it should have a backbone area
that backbone aerial must exit tiuna Any Internet work using West PF
over multiple areas as a routing protocol.
As you can see in this diagram, communication between Area one and the two monster flow through area Zero
of these communication can be internal to a single rotter that as interfaces directly connected the area 01 on too right

Leave the O S. P. F area. Zero pottery was extending into the branch, then the branch router would have to do SPF calculations for air A zero on its own area. On the essays would've flowed over the one link,
the second of design considerations and not to a group of remote branches into a single area having all remote branches in the same areas and Allah scaleable since they had a place each remote branch in eight only area to limit our essay Flooding and SPF recalculations
