Issues with Site-to-Site Connections

Summary

This chapter showed you the basics of setting up L2L sessions on routers. I've focused primarily on the ISAKMP/IKE Phase 2 components for building these connections. The order of the chapter has led you through the features as they became available in the Cisco IOS: static crypto maps, dynamic crypto maps, TED, GRE across IPsec, and DMVPN.

Next up is Chapter 18, "Router Remote Access Connections," where I show you how to configure your router to be an Easy VPN Server or Remote (Client).
