1). Cisco CCNP / BSCI Certification: The Local Preference BGP Attribute
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".

2). Cisco CCNP / BSCI Exam Tutorial: Filtering BGP Updates With Prefix Lists
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.

3). Cisco CCNP / BSCI Exam Tutorial: Introduction To Policy Routing
Policy routing is a major topic on your BSCI exam, and you'll find quite a bit of policy routing going on in today's production networks. But what exactly is policy routing?
Policy-based routing, generally referred to as "policy routing", is the use of route maps to determine the path a packet will take to get to its final destination. As you progress.

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

5). Cisco CCNP Certification / BSCI Exam Tutorial: An Introduction To BGP
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.

6). Cisco CCNP Certification: BGP Attribute Category Tutorial
To pass the CCNP exams, you’ve got to master BGP. The first step is understanding the major BGP attribute categories. Learn the details you need to know to pass the exam from Chris Bryant, CCIE #12933.

7). CCNP Certification / BSCI Exam Tutorial: The BGP Neighbor Process
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.

8). Cisco CCNP / BSCI Tutorial: The BGP Attribute NEXT_HOP
When you're studying for the BSCI exam on the way to earning your CCNP certification, you've got to master the use of BGP attributes. These attributes allow you to manipulate the path or paths that BGP will use to reach a given destination when multiple paths to that destination exist.
In this free BGP tutorial, we're going to take a look at the NEXT_HOP attribute.

9). Cisco CCNP Certification: Using The BGP Command “Update-Source”
When you start preparing for your CCNP exam, particularly the BSCI exam, you're introduced to Border Gateway Protocol (BGP) configurations. BGP is unlike any protocol you learned during your CCNA studies, and even the similarities are a little bit different!
BGP forms neighbor relationships, much like EIGRP and OSPF do. The interesting thing with BGP is that potential neighbors, or "peers", do not need to be directly connected and can use their loopback interfaces to form the peer relationships.

10). Cisco CCNA Certification: The Path To Take After Earning The CCNA
Once you earn your CCNA certification, you've got quite a few exciting choices ahead of you! The majority of CCNAs go on to pursue another Cisco certification, and this is a wise decision. The more you know, the more valuable you are in today's IT market.
A question I'm often asked by new CCNAs is "Which certification should I go after next?" Often, these new CCNAs have their eye on the Cisco Certified Security Professional (CCSP) certification.

11). Cisco CCNP / BSCI Certification: The BGP Attribute “MED”
When you're preparing to pass the BSCI exam and earn your CCNP certification, one of the biggest challenges is learning BGP. BGP is totally different from any protocol you learned to earn your CCNA certification, and one of the differences is that BGP uses path attributes to favor one path over another when multiple paths to or from a destination exist.

12). Cisco CCNP / BSCI Exam Tutorial: BGP Adjacency States
To pass the BSCI exam, earn your CCNP certification, and become an outstanding networker, you've got to master the many details of BGP - and trust me, there are a lot of details to master! Before you get into the more advanced features of BGP, you should have the fundamentals down cold, and one of those fundamentals is knowing the BGP adjacency states.

13). Cisco CCNP / BSCI Certification: BGP Route Reflector Tutorial
When you're studying for your BSCI exam and CCNP certification, you quickly realize that BGP is a whole new world from anything you've previously studies. One topic that sometimes confuses CCNP candidates is when a BGP route reflector needs to be configured.
In the following example, the routers R1, R2, and R3 are all in BGP AS 100. This is not a full mesh, however.

14). Cisco CCNP Certification: The BGP Weight Attribute
When you're studying for the CCNP certification, especially the BSCI exam, you must gain a solid understanding of BGP. BGP isn't just one of the biggest topics on the BSCI exam, it's one of the largest. BGP has a great many details that must be mastered for BSCI success, and those of you with one eye on the CCIE must learn the fundamentals of BGP now in order to build on those fundamentals at a later time.

15). Cisco CCNP / BSCI Exam Tutorial: The BGP Attribute MED
Your BSCI exam and CCNP certification success depend on mastering BGP, and a big part of that is knowing how and when to use the many BGP attributes. And for those of you with an eye on the CCIE, believe me - you've got to know BGP attributes like the back of your hand. One such BGP attribute is the Multi-Exit Discriminator, or MED.
The MED attribute is sent from a router or routers in one AS to another AS to indicate what path the remote AS should use to send data to the local AS.
