Hello, my r1 now we're going to do summarization, right? So that's what this section is all about how to summarize using the binary method, and we're gonna use a lab to explain that. Okay. But the binary method, that there's a you go online, you're gonna find 3 Million Ways To summarize 3 Million Ways to submit 3 Million Ways to do whatever. I'm telling you this right now, the binary method, you will never be wrong unless you made the mistake in your math and you always need to double check yourself. Okay?

I'm always double checking myself. Always because we all were human beings, we made mistakes. So make sure you do things right. But the binary method, it is the best way because guess what? routers computers, any techie any tech, they talk, zeros and ones. Okay.

So that's the best way to do it. Always use a lab, and you'll see how it's done. And then we're going to look using a simulator. All right out of summarization lab. And the importance of it is extremely important, especially in big networks, where you have edge routers, core routers, all these things, you're sending thousands upon thousands of routes out to your providers, or your edge routers, or whatever the case may be. These internet backbone routers, where you think they're going down all the time, because they have 10s of thousands, if not hundreds of thousands of routes in the routing table.

They really did not build a hierarchy that's always ipv6 took so long is still taking long to make sure that those internet routers have a hierarchy. Okay. Oh, they're in their routing tables and they look at certain things. Well, summarization is going to help us to help those routers that are out they're not have to look at 100 200 1000 routes, maybe they can look at two Route 20 routes one route, it all depends. So it's very important, and we'll do that in a particular simulator. Okay, I'll see you there.
