1). Cisco CCNA / CCNP Home Lab Setup: How To Configure Reverse Telnet By : Chris Bryant, CCIE #12933
Occasionally, during your CCNA and CCNP studies, you'll run into a term that just doesn't quite make sense to you. (Okay, more than occasionally!) One such term is "reverse telnet". As a Cisco certification candidate, you know that telnet is simply a protocol that allows you to remotely connect to a networking device such as a router or switch. But.

2). Cisco CCNP / BSCI Exam Tutorial: OSPF Route Redistribution Review By : Chris Bryant, CCIE #12933
OSPF route redistribution is an important topic on the BSCI exam, and it's a topic full of details and defaults that you need to know for the exam room and the job. To help you pass the BSCI exam, here's a quick review of some of the OSPF route redistribution basics. To see if a router is an ABR or ASBR, run show ip ospf. This also displays any routes being redistributed into OSPF on this router.

4). Cisco CCNA Certification: Defining Broadcast Domains By : Chris Bryant, CCIE #12933
When you're studying to pass the CCNA exam and earn your certification, you're introduced to a great many terms that are either totally new to you or seem familiar, but you're not quite sure what they are. The term "broadcast domain" falls into the latter category for many CCNA candidates. A broadcast domain is simply the group of end hosts that will receive a broadcast sent out by a given host.

5). Cisco CCNP / BSCI Exam Tutorial: The Passive Interface Command And OSPF By : Chris Bryant, CCIE #12933
To pass the BSCI exam and become a CCNP, you have to be aware of the proper use of passive interfaces. You learned about passive interfaces in your CCNA studies, but here we�ll review the basic concept and clear up one misconception regarding passive interfaces and OSPF. Configuring an interface as passive will still allow the interface to receive routing updates, but the interface will no longer transmit them.

6). Cisco CCNP / BSCI Certification: The Local Preference BGP Attribute By : Chris Bryant, CCIE #12933
When studying for your BSCI exam for the CCNP, you get your first taste of BGP. One of the major differences between BGP and the other protocols you've studied to date is that BGP uses attributes to describe paths, and to influence the selection of one path over the other. In this free tutorial, we're going to take a look at the Local Preference attribute and compare it to the Cisco-proprietary BGP attribute "weight".

7). Cisco CCNA Certification: How And Why Switches Trunk By : Chris Bryant, CCIE #12933
Your CCNA studies are going to include quite a bit of information about switches, and for good reason. if you don't understand basic switching theory, you can't configure and troubleshoot Cisco switches, either on the CCNA exam or in the real world. That goes double for trunking! Trunking is simply enabling two or more switches to communicate and send frames to each other for transmission to remote hosts.

8). Cisco CCNP / BSCI Exam Tutorial: Using The OSPF Command �Area Range� By : Chris Bryant, CCIE #12933
Your BSCI and CCNP exam success depends on knowing the details, and one such detail is knowing the proper way to summarize routes in OSPF. Route summarization is not just a test of your binary conversion abilities, but knowing where and when to summarize routes. It will not surprise any CCNA or CCNP certification candidate that OSPF gives us the most options for route summarization, and therefore more details to know! OSPF offers us two options for route summarization configurations.

9). Cisco CCNA / CCNP Certification: OSPF E2 vs. E1 Routes By : Chris Bryant, CCIE #12933
OSPF is a major topic on both the CCNA and CCNP exams, and it's also the topic that requires the most attention to detail. Where dynamic routing protocols such as RIP and IGRP have only one router type, a look at a Cisco routing table shows several different OSPF route types. R1#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M -.

10). Cisco CCNA / CCNP Home Labs: Developing Troubleshooting Skills By : Chris Bryant, CCIE #12933
CCNA / CCNP candidates are going to be drilled by Cisco when it comes to troubleshooting questions. You're going to have to be able to analyze configurations to see what the problem is (and if there is a problem in the first place), determine the meaning of different debug outputs, and show the ability not just to configure a router or switch, but troubleshoot one.

11). Cisco CCNP / BSCI Exam Tutorial: EIGRP Route Summarization By : 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.

12). Cisco CCNP Certification / BSCI Exam Tutorial: Comparing IRDP And HSRP By : Chris Bryant, CCIE #12933
To pass the BSCI exam, you need to know the difference between IRDP and HSRP. While they have the same basic function, the operation and configuration of each are totally different. The aim of both is to allow hosts to quickly discover a standby router when the primary router fails. IRDP is commonly used by Windows DHCP clients and several Unix variations, but you do see it in Cisco routers as well.

14). Cisco CCNP / BSCI Exam Tutorial: Using OSPF's "Summary-Address" Command By : Chris Bryant, CCIE #12933
BSCI exam success, not to mention earning your CCNP, can come down to your OSPF route summarization skills. There are a few different commands and situations you need to be ready for, and one of these situations is the proper use of the "summary-address" command. The summary-address command should be used on an ASBR in order to summarize routes that are being injected into the OSPF domain via redistribution.

15). Tips On Buying A Cisco CCNA / CCNP Home Lab Kit By : Chris Bryant, CCIE #12933
Buying a CCNA / CCNP home lab is the best way to be totally prepared for your Cisco exams. Most home labs are put together one router or switch at a time, but many CCNA / CCNP candidates prefer to buy kits where you get multiple routers and switches, along with all the cables and other connection devices you'll need. While this is a good idea, keep a few things in mind when purchasing Cisco home lab kits.

16). CCNP Certification / BSCI Exam Tutorial: The BGP Neighbor Process By : Chris Bryant, CCIE #12933
Like TCP, BGP is connection-oriented. An underlying connection between two BGP speakers is established before any routing information is exchanged. This connection takes place on TCP port 179. As with EIGRP and OSPF, keepalive messages are sent out by the BGP speakers in order to keep this relationship alive. Once the connection is established, the BGP speakers exchange routes and synchronize their tables.

17). Cisco CCNP Certification / BSCI Exam Tutorial: An Introduction To BGP By : Chris Bryant, CCIE #12933
When you're studying for the BSCI exam on the way to earning your CCNP certification, it's safe to say that BGP is like nothing you�ve studied to this point. BGP is an external routing protocol used primarily by Internet Service Providers (ISPs). Unless you work for an ISP today or in the future, you may have little or no prior exposure to BGP. Understanding BGP is a great addition to your skill set � and you have to know the basics well to pass the BSCI exam.

18). CCNP / BSCI Exam Tutorial: Route Summarization And The OSPF Null Interface By : Chris Bryant, CCIE #12933
CCNP exam success, particularly on the BSCI exam, demands you understand the details of route summarization. This skill not only requires that you have a comfort level with binary conversions, but you have to know how and where to apply route summarization with each individual protocol. You also have to know the "side effects" of route summarization.

20). Cisco CCNP / BSCI Exam Tutorial: Filtering BGP Updates With Prefix Lists By : Chris Bryant, CCIE #12933
A major part of your BSCI and CCNP exam success is mastering BGP, and that includes filtering BGP routing updates. In this tutorial, we'll take a look at how to filter BGP updates with prefix lists. R4 is advertising three networks via BGP. The downstream router R3 sees these routes and places them into its BGP table as shown below. R3 has two downstream BGP peers, R1 and R2, and is advertising itself as the next-hop IP address for all BGP routes sent to those two routers.

21). Cisco CCNP / BSCI Exam Tutorial: Not All Static Routes Are Created Equal By : Chris Bryant, CCIE #12933
As a CCNP candidate, as a CCNA, and in getting ready to pass the BSCI exam, you may be tempted to breeze through your static route studies, or even skip them! That's because static routes are easy enough to configure, and as long as you remember the syntax of the ip route command, you're in good shape. But there's one vital detail regarding static routes that many exam candidates miss.

22). Cisco CCNA / CCNP Certification Exam Review: Protocol Basics By : Chris Bryant, CCIE #12933
To earn your Cisco CCNA certification and pass the BSCI CCNP exam, you have to know your protocol basics like the back of your hand! To help you review these important concepts, here's a quick look at the basics of RIPv1, RIPv2, IGRP, and EIGRP. RIPv1: Broadcasts updates every 30 seconds to the address 255.255.255.255. RIPv1 is a classful protocol, and it does not recognize VLSM, nor does it carry subnet masking information in its routing updates.
