Part IV will discuss the use of Cisco IOS-based routers to initiate and terminate VPN sessions. Cisco routers are very flexible and can be used for site-to-site (LAN-to-LAN or L2L) sessions, VPN gateways, and remote access clients. I'll focus primarily on how to configure Cisco routers using the IOS CLI interface; however, other GUI-based products, such as Security Device Manager (SDM) and CiscoWorks VMS Router Management Center (MC), can be used to configure VPNs on routers.
In this chapter, however, I'll introduce you to the Cisco router product line that supports VPN capabilities. I'll discuss some typical VPN deployment scenarios used with Cisco routers, and some of the advantages they have over other Cisco VPN products.
