In this bonus video for StormWind.com CCNA students - Anthony Sequeira walks you through the site to site VPN configuration.
In this video, Anthony Sequeira and Guest Experts from StormWindLive explain VPNs for CCNA students.
In this post, Anthony Sequeira examines a fast and easy approach to a WAN configuration in an exam sim. Let us pretend we are in the CCNA testing environment and we need to build a WAN circuit. Since we are under huge time pressures in the exam, it goes without saying that we need to do this very quickly and very efficiently. Here are some steps we can use to build speed and accuracy on our first attempt at the task Sample Sim Task: Build a PPP WAN circuit between R1 and R2 using the S0/0 interfaces respectively. Use CHAP authentication with a secret of cisco. R1 should challenge the client of R2. Use 192.168.1.1/24 on R1 and 192.168.1.2/24 on R2 for the addressing. With my configuration approach, I am going to use a "bottom up" approach and use the OSI model layers to help ensure I do not forget anything. OK, I will start on R1 the CHAP "server".
In this Cisco Video Blog, Anthony Sequeira demonstrates the difference between frame-relay map and frame-relay interface-dlci.
This post aims to help our CCNA students when it comes to Frame Relay terminology.CCNA students consistently report that one of their trouble areas in the exam is Frame Relay and its terminology. It is second only to subnetting when it comes to student reports of exam difficulties. In this Epic Live Blog post, I am going to cover the terms you should know about Frame Relay for the real world and your certification exam, and of course, I am going to use plain English and simple analogies to assist you.
Data Terminal Equipment (DTE)
DTE equipment is electronic stuff that needs to connect to the Frame Relay network in order to communicate. In our case, we often think of our Cisco router as the DTE. The DTE could also be a multiplexor, concentrator, bridge, or even simply a Frame Relay I/O board in some other piece of networking equipment.
Data Communications Equipment (DCE)
This is typically what we term the Frame Relay networking devices of the Frame Relay Service Provider. These DCE devices provide clocking and switching services to the DTE equipment and they make sure our happy little data frames make their way safely through the big and scary Wide Area Network (WAN).
