Summary

In this chapter, you learned various implementations of Layer 3 protocols over ATM. Specifically targeted toward the CCIE Security lab exam, the chapter concentrated on two methods of ATM deployment: multiprotocol encapsulation (RFC 2684) and Classical IP (RFC 2225). RFC 2684 encompasses multiple protocols, and RFC 2225 focuses on IP only. Both of these implementations included a discussion on permanent virtual circuits (PVCs) and switched virtual circuits (SVCs), their configurations, and monitoring and troubleshooting techniques.
