Cisco ccnp bsci exam tutorial eigrp route summarization


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.


Ccnp, bsci, exam, pass, route, summarization, summarize, binary, conversion, eigrp, ospf, external, route, summary, address


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


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

Cisco CCNP / BSCI Exam Tutorial: Route Summarization


To pass the BSCI exam and earn your CCNP certification, youve got to master route summarization. Learn how to create the summary routes and apply them correctly from Chris Bryant, CCIE #12933.


Ccnp, exam, bsci, video, route, summary, summarization, rip, eigrp, ospf, area, range, address, pass, free


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

Cisco CCNP / BSCI Certification: Troubleshooting Route Redistribution, Part I


Route redistribution looks easy, but there are details you must master to pass the CCNP exams and become a master networker. Learn how to troubleshoot one common redistribution error from Chris Bryant, CCIE #12933.


Ccnp, bsci, exam, certification, pass, route, redistribution, subnets, ospf, rip, bgp, table, show, ip , route, version, 2


If there's one CCNP / BSCI topic that looks so easy but can lead to a real headache, it's route redistribution. I'm not even talking about the routing loops and suboptimal routing that can result when route redistribution is done without proper planning - I'm talking about the basic commands themselves. Leaving out one single command option, or forgetting what else needs to be redistributed when redistributing dynamically discovered routes, can leave you with a routing table that looks complete but does not result in full IP connectivity.

In this free CCNP / BSCI tutorial series, we'll take a look at three common errors in route redistribution configurations, and how to fix them. We'll use three routers, R1, R3, and R5. R1 and R5 are in a RIPv2 domain and R1 and R3 are in an OSPF domain. R1 will be performing two-way route redistribution.

R5 is advertising its loopback, 5.5.5.5/24, into the RIPv2 domain. R1 sees this route in it

The stunning Garden Route runs from South Africas most popular tourist destination, Cape Town, for 800 km along the scenic coastline between this city and Port Elizabeth. The area enjoys a Mediterranean maritime climate and the trip is regarded as one of the worlds truly classic coastal drives.


As you drive along the well-forested coastal plain, youll find freshwater lakes, lovely lagoons filled with water birds, indigenous forests of giant yellowwood trees and fields covered in colourful wildflowers. Its easy to see why visitors are drawn to this beautiful region year-round.


One of the highlights of a drive along the Garden Route is a stop at the sleepy coastal town of Hermanus near the southern-most tip of Africa. The town is situated next to a 12-km path that runs along the cliff top, right next to the ocean. From May to December, pods of Southern Right Whales swim to within 20 metres of the cliff as they travel along the coast.


The more adventurous traveller can try some heart-stopping shark cage diving, sea kayaking, abseiling, scuba diving, sand boarding, and paragliding. Those looking for something more relaxing to do can visit the vineyards in a nearby valley and do the short drive to the southernmost tip of Africa, where the Atlantic Ocean meets the Indian Ocean.


You will have to drive inland to visit Oudtshoorn, which was built in the early 1800s, in the centre of the Klein Karoo, a semi-desert area wedged between the coastal mountains to the south and the spectacular Swartberg mountain range to the north. The town was the world capital of the Ostrich feather industry during Victorian times, and many grand houses from that era are still standing today. Theres plenty to do in Oudtshoorn you can try riding an ostrich at an ostrich farm, take a tour through the magnificent Cango Caves that stretch for kilometres throughout the mountains, visit the vineyards, and even stroke a Cheetah at Cheetahland.


Back on coast, the Garden Route takes you to George, located on a 10-km plateau that runs from the majestic Outeniqua Mountain to the Indian Ocean. Besides enjoying whale watching, surfing, swimming, scuba diving and paragliding, youll find three of South Africas top golf courses are also located here. The Fancourt Golf Estate is especially popular, with an 18-hole course designed by Gary Player, a golf academy, exclusive hotel and conference centre, restaurants, and numerous sporting facilities.


Further along the coast toward Port Elizabeth is the town of Knysna, also a very popular tourist destination. This laid-back town is situated between a lush indigenous forest, home to the last of the forest-dwelling elephants in Africa, and a beautiful lagoon teeming with birds and other wildlife. The oysters grown in this unpolluted lagoon are among the tastiest in the world. The closest beach is in nearby Buffalo Bay, a favourite spot for fishing, surfing and swimming, as well as whale and dolphin watching. The entire area surrounding Knysna, with its incredible biological richness and beauty, is a paradise for the eco-traveller, with plenty of places to camp, hike, canoe, kayak, and observe the unique wildlife.


At Plettenberg Bay, there are ten important nature reserves as well as marine reserves. The endangered Southern Right Whale calves in the bay from July to December, and seals and dolphins live here all year round. In the bay you can snorkel and scuba dive on unique soft coral reefs, and on the beach youll find a wide range of water sports on offer, including fishing, surfing, swimming and sailing. Nearby, there are superb hiking and mountain biking trails, horse riding, kayaking and canoeing in scenic Natures Valley and Stormsriver.


Your drive along the Garden Route ends in Port Elizabeth, on the shores of beautiful Algoa Bay.
