Router ISAKMP/IKE Phase 1 Connectivity

Router ISAKMP IKE Phase 1 Connectivity

This chapter is the first chapter on configuring routers for VPN implementations, where I'll focus on setting up ISAKMP/IKE Phase 1 to establish a management connection to a remote IPsec peer (site-to-site or remote access). I assume that you have a basic understanding of the Cisco IOS.

In this chapter, I'll discuss the commands that are used to create an ISAKMP/IKE Phase 1 policy for your management connection and the three types of supported device authentication: pre-shared keys, RSA encrypted nonces, and RSA signatures. I'll also briefly discuss how to manage and monitor your management connections. I'll wrap up the chapter discussing a new feature of the IOS, where you can have a Cisco IOS router perform the functions of a certificate authority (CA) or registration authority (RA).


Even though I'll briefly discuss some show and debug commands in this chapter, I'll reserve most of this discussion for Chapter 19, "Troubleshooting Router Connections."
