1). Passing Your CCNA and CCNP: Configuring And Troubleshooting Router-On-A-Stick
For CCNA and CCNP candidates, it's hard not to laugh the first time you hear the phrase "router on a stick". Let's face it, that's a pretty silly term. But as those who have passed the CCNA and CCNP exams know, this is a vital exam topic that you must know how to configure and troubleshoot.
Basic Cisco theory states that for hosts in different VLANs to communicate, a Layer 3 device must be involved to handle the routing between the VLANs.

2). Cisco CCNP / BCMSN Exam Tutorial: Changing Root Bridge Election Results
Your BCMSN and CCNP studies will include mastering the details of Spanning Tree Protocol (STP). While you learned some of these details in your CCNA studies, quite a bit of it may be new to you. Before going on to the intermediate and advanced STP features, let's review the root bridge election process and learn how to change these results.
Each switch will have a Bridge ID Priority value, more commonly referred to as a BID.

3). Passing Cisco's CCNA and CCNP Exams: The VLAN.DAT File
CCNA and CCNP candidates are often confused about why VLANs and VTP information is still present on a switch after the configuration is erased. Learn why this happens and how to really delete VLAN information in this free tutorial from Chris Bryant, CCIE #12933.

4). Cisco CCNA Certification Exam Tutorial: Configuring And Troubleshooting VTP
Not only is your CCNA exam going to have questions on VLAN trunking protocol, almost any network that has more than one VLAN is going to have VTP running. Whether you're planning on passing the CCNA exam or just brushing up on your networking skills, this VTP tutorial will help you learn the basics of this important protocol.
VTP allows switches to advertise VLAN information between other members of the same VTP domain.

5). Cisco CCNA / CCNP / BCMSN Exam Review: Trunking And Trunking Protocols
To earn your CCNA or CCNP certification, you've got to understand the basics of trunking. This isn't just a CCNA topic - you must have an advanced understanding of trunking and etherchannels to pass the BCMSN exam and earn your CCNP as well. Before we address those advanced topics, though, you need to master the fundamentals!
A trunk allows inter-VLAN traffic to flow between directly connected switches.

6). Cisco CCNA Exam Tutorial And Case Study: VLANs and IP Connectivity
In this CCNA case study, we'll take some basic switching and trunking theory and put it into action. We have two routers (R2 and R3) along with two switches (SW1 and SW2). R2 is connected to SW1 at fast 0/2, and R3 is connected to SW2 at fast 0/3. Both routers have IP addresses on the 172.12.23.0 /24 network.
For these routers to be able to ping each other, the switches must be able to communicate.

7). Cisco CCNP / BCMSN Exam Tutorial: Dynamic VLANs and VMPS
Knowledge of Dynamic VLANs and VMPS is important in your efforts to pass the BCMSN exam and earn your CCNP, and it's also a great skill to have for your networking career.
As a CCNA and CCNP candidate, you know how and why to configure static VLANs. Static VLANs can be a powerful tool for reducing unnecessary broadcast and multicast traffic, but if hosts are moved from one switch port to another, you've got to make those changes manually on the switch.

8). CCNP / BCMSN Exam Tutorial: VLAN Trunking Protocol (VTP)
Passing the BCMSN exam and getting one step closer to the CCNP certification means learning and noticing details that you were not presented with in your CCNA studies. (Yes, I know – you had more than enough details then, right?) One protocol you’ve got to learn more details about is VTP, which seemed simple enough in your CCNA studies! Part of learning the details is mastering the fundamentals, so in this tutorial we’ll review the basics of VTP.

9). Cisco CCNP / BCMSN Exam Tutorial: Static VLANs
BCMSN exam success and earning your CCNP certification requires you to add to your knowledge of VLAN configuration. When you studied for your CCNA exam, you learned how to place ports into a VLAN and what the purpose of VLANs was, but you may not be aware that there are two types of VLAN membership. To pass the BCMSN exam, you must know the details of both types.

10). CCNA / CCNP Home Lab Tutorial: The VLAN.DAT File
CCNA and CCNP candidates who have their own Cisco home labs often email me about an odd situation that occurs when they erase a switch's configuration. Their startup configuration is gone, as they expect, but the VLAN and VTP information is still there!
Sounds strange, doesn't it? Let's look at an example. On SW1, we run show vlan brief and see in.
