Site-To-Site VPN via CCP

security-gallery-01258I have ran through before on how to create a site-to-site VPN with Cisco SDM which sounds like a repeat but I thought why not bring CCP into light and since I’m studying the newly created CCNA Security (640-554) I figured let’s create a tutorial on it. In this lab I am going to post the running-config of both locations so you can either run it through Packet Tracer or live equipment if you wish. I am running two Cisco 2811s with Advanced Security Version 12.4(24)T8. Let’s do it! Continue reading

Types of WAN Links

I’ve found this table that I created a while ago and it lists common WAN connections that businesses use. I have used this table like a reference guide to familiar myself into other protocols. People don’t think of it much but the WAN is a different beast compared the LAN as it uses different protocols besides Ethernet. The WAN or wide area network is what connects us to remote locations within a organization. If we have an office in New York and another office in Wyoming  we need these offices to be connected to each other so that they seem to be on the same network even though they are miles away these types of WAN connections and protocols  would do it.

Along with the United States of America which is also moving forward with the National Broadband Plan. So today let’s explore the wireless concepts! Continue reading

Creating VLANs

Today this tutorial is going to be talking about creating VLANs (Virtual Local Area Networks) with a Cisco Catalyst switch. By creating a VLAN you are separating the network, why would you do this? There are some several reasons, like separating your production network from a guest network, and separating a test environment from a production network. This all adds security to your network. You can separate core critical network components from the rest of the production network for added security, easier troubleshooting along with separating or segmenting your network. This is breaking up the broadcast domains into smaller chucks, which will improve your network performance. Let’s get started! Continue reading
