After sitting down and talking this out with the wife we both think it would be irresponsible at this point to spend another $2000 on a bootcamp, plus another $1500 in travel relate expenses. With the baby coming in August it just wouldn’t make sense to spend this extra money. It just doesn’t add up. My wife seems to have more faith in me than myself. She keeps telling me I wouldn’t need a bootcamp. She is convinced at this point I am just getting “psyched” out about everything read about this exam. She might be right… I have the end-to-end program from IE so I just decided right now to use all the materials I have on hand. She did ask why not offer to review a bootcamp for a discount ;). I just laughed at her! With my literary skills it would do them more harm than good!

Frame Relay does not natively support features such as authentication, link quality monitoring, and reliable transmission. Based on this it is sometimes advantageous to encapsulate an additional PPP header between the normal layer 2 Frame Relay encapsulation and the layer 3 protocol. By running PPP over Frame Relay (PPPoFR) we can then implement authentication of Frame Relay PVCs, or even bind multiple PVCs together using PPP Multilink.

PPPoFR is configure in Cisco IOS through the usage of a Virtual-Template interface. A Virtual-Template is a PPP encapsulated interface that is designed to spawn a “template” of configuration down to multiple member interfaces. The traditional usage of this interface has been on dial-in access servers, such as the AS5200, to support multiple PPP dialin clients terminating their connection on a single interface running IP.

The first step in configuring PPPoFR is to create the Virtual-Template interface. This interface is where all logical options, such as IP address and PPP authentication will be configured. The syntax is as follows:

interface Virtual-Template1
 ip address 54.1.7.6 255.255.255.0
 ppp chap hostname ROUTER6
 ppp chap password 0 CISCO
