Cisco CCNP / BSCI Exam Tutorial: EIGRP Route Summarization

Its not enough to know how to summarize routes to pass the BSCI exam, you need to know the commands for each protocol! Learn how to summarize routes in EIGRP with Chris Bryant, CCIE #12933.

Summarizing routes is a vital skill to learn to pass the BSCI exam and get one step closer to earning your CCNP. The actual binary conversions are only part of the test, though! You've got to know how to correctly apply the summary routes, and that differs from one protocol to the next. In the last few CCNP / BSCI tutorials, we've looked at using the "area range" and "summary-address" commands to perform OSPF route summarization. Today, we'll take a look at summarizing routes in EIGRP.

We'll use the following four loopback addresses in this example:

Loopback 16, 16.16.16.16 /32

Loopback 17, 17.17.17.17 /32

Loopback 18, 18.18.18.18 /32

Loopback 19. 19.19.19.19 /32

On R1, we'll place these four addresses into EIGRP AS 100.

R1(config-if)#router eigrp 100

R1(config-router)#network 16.16.16.16 0.0.0.0

R1(config-router)#network 17.17.17.17 0.0.0.0

R1(config-router)#network 18.18.18.18 0.0.0.0

R1(config-router)#n

Cisco CCNP Certification / BSCI Exam Tutorial: Route Summarization Basics

To pass the BSCI exam and earn your CCNP certification, youve got to master the basics of route summarization. Learn how to do just that in this article from Chris Bryant, CCIE #12933.

Ccnp, ccna, exam, pass, free, certification, route, summarization, rip, igrp, eigrp, ospf

As you earn your CCNA and CCNP certification, you're going to have to get comfortable with manually summarizing routes. This isn't just another reason to learn binary math (although it's a good one!), but summarizing routes is a true real-world skill that can help your network operate more efficiently. So the question isn't just how to summarize routes, it's why.

When you summarize routes in RIP, IGRP, EIGRP, or OSPF, you're replacing a series of routes with a summary route and mask. With RIP, IGRP, and EIGRP, this actually lessens the size of the routing update packet itself - multiple routes are replaced with the summary route. For instance, the routes 8.0.0.0/8, 9.0.0.0/8, 10.0.0.0/8, and 11.0.0.0/8 can be summarized as 8.0.0.0 252.0.0.0. Only the summary address will be found in the update packet, making it concise yet complete.

Summarizing routes can also make the routing table smaller, yet still allow for complete IP connect

Preparing to pass the BSCI exam and earn your Cisco CCNP? Route summarization is just one of the many skills you'll have to master in order to earn your CCNP. Whether it's RIP version 2, OSPF, or EIGRP, the BSCI exam will demand that you can flawlessly configure route summarization.

Route summarization isn't just important for the BSCI exam. It's a valuable skill to have in the real world as well. Correctly summarizing routes can lead to smaller routing tables that are still able to route packets accurately - what I like to call "concise and complete" routing tables.

The first skill you've got to have in order to work with route summarization is binary math more specifically, you must be able to take multiple routes and come up with both a summary route and mask to advertise to downstream routers. Given the networks 100.16.0.0 /16, 100.17.0.0 /16, 100.18.0.0 /16, and 100.19.0.0 /16, could you quickly come up with both the summary address and mask? All you need to do is break the four network nu
