CHAPTER 1
Overview of Cisco 3600 Series Routers
Cisco 3600 series routers are modular access routers with LAN and WAN connections that can be
configured by means of interchangeable modules and WAN interface cards. With over 70 modular
interface options, Cisco 3600 series routers provide solutions for data, voice, video, hybrid dial access,
Virtual Private Networks (VPNs), and multiprotocol data routing.

Chapter 1 Overview of Cisco 3600 Series Routers Memory Memory This section describes the various types of memory that may be present in a Cisco 3600 series router. Memory Types Cisco 3600 series routers support the following types of memory: • DRAM or SDRAM—Stores the running configuration and routing tables, and is used for packet buffering by the router’s network interfaces. The Cisco IOS software executes from DRAM. • Nonvolatile random-access memory (NVRAM)—Stores the system configurati
