Add You - Cisco CCNP Certification: Introduction To BGP
Here are several steps to take in order to properly determine whether the fixer-upper house that has caught your attention deserves a seal of approval or a thumbs-down sign:“Location, Location, Location” is Still the MantraIt doesn’t matter if you’re investing in an apartment, a condominium unit or in this case, a fixer-upper home. When it comes to real estate property, the mantra you still have to recite to yours
A good way to look at it is that networks are contained in Autonomous Systems BGP helps you find the AS where a given network is found. Routing protocols such as OSPF and EIGRP take it from there.

Niche marketing in a nutshell is setting ourselves up to be the Big Fish in a Little Pond. As business owners, we need to take the time to plan how we will assume the role of expert and problem solver for our niche market.“By failing to prepare, you are preparing to fail” ~ Benjamin FranklinWith all the talk about niche marketing, it seems that we could all sit and spin our wheels everyday without making much p
Whenever I teach distance-vector protocols in my Ultimate CCNA Boot Camp or Fast Track classes, I make sure my students understand the many rules of distance-vector routing thoroughly. After that, we move on to OSPF and link-state routing.
And what do I tell my students before we move on to OSPF and link-state? "Take all that great stuff you just learned about distance-vector routing and put it aside, because none of it applies here!"
That's about the time I get astonished looks and a few things thrown at me. :)
What's this got to do with BGP? Well, when you start studying BGP, you have to put a lot of preconceptions aside. It sounds like just another routing protocol, like RIP or OSPF, but it's not.
So... before we start studying BGP and looking at some of its many features, let's take a look at what BGP is and what it's not.
What BGP Does And Who Uses It
If you're in a position where you're used to seeing or working with routing protocols such as EIGRP and OSPF, you're probably now working with BGP. BGP is not a protocol you're going to configure at the office LAN. BGP is used to connect autonomous systems, which are very large "collections" of networks. (Those of you who have studied IGRP and EIGRP are familiar with the concepts of an AS.)
As opposed to routing protocols such as EIGRP and OSPF, BGP is an exterior routing protocol. BGP is not used to find a specific network instead, it's used to find the AS where that given network can be found.

Have you ever gotten one of those letters from your local property tax appraiser, informing you that your tax bill is going up about 20 percent?I got one of those recently, so I took it to my friend Joe Gross in San Antonio. He appeals property tax assessments for a living."Man," he said. "I've never seen assessments shoot up like they have this year."My "news antennae" shot up. Then when he showed m

People with an online presence realize the importance of having a professional looking website and often pay programmers to build sites for them but this can be very expensive for someone just starting out. A less expensive alternative is to purchase a website creation software package such as XSitePro which is said to be designed for internet marketers and simple to use without having programming experience. If you decide to g

1) CREATE A WEBSITE This will act as a Portfolio and lists all the items you created and want to sell. Make it detailed and list the pricing information for those interested in purchasing. You can even add a shopping cart and get fancy with features you'd like to present to your audience like an "about" page for example. Add shipping information, and a section for those who would like to buy in bulk

BGP Terminology
You'll be happy to know that BGP has a terminology all its own. Well, you might not be happy about it, but it does! I'm not going to throw a bunch of terms at you right now, since these terms are better introduced to you when you can see what they do. Having said that, here are a couple of basic BGP terms that will help you make the transition from IGPs to BGP.
aggregation - This is just the BGP term for summarization. You're familiar with route summarization from your CCNA studies, and if not, it's time for a review from my Ultimate CCNA Study Guide. I told you you'd be using those skills for a long time!
IGP - Interior Gateway Protocol. These are routing protocols that run within an Autonomous System, such as OSPF and EIGRP.
EGP - Exterior Gateway Protocol. Remember from your CCNA studies that EIGRP routes are indicated by the letter "D" in your routing table? Ever wonder why? EGP, that's why. Run show ip route and take a look at the routing table key. EGP was BGP's predecessor, and is still in the routing table. EGP was there before EIGRP, so that's why "E" in the routing table doesn't indicate an EIGRP route.
We'll be adding to this list a great deal in the next few weeks.
Now that you've got a grasp on the differences between BGP and the IGPs you've been working with up to this point, it's time to start looking at some basic BGP concepts and configurations. Look for Part II of this BGP tutorial over the next few days!
