Chapter 2: Configuring Your Routers

Introduction

By now, you should have configured your CNA system as described in Chapter 3: Configuring a New CNA Server Device of the CNA Fundamentals Guide.

Your next step is to add the following to your edge routers:

• GRE tunnel interfaces that will connect to the USTAT modules
• route maps for policy routing on the tunnels
• routing between the edge routers and the CNA system, including iBGP peering and routing to the USTAT VIPs

For the purposes of describing the CNA configuration process using widely understood terminology, this documentation assumes a simple, generic network that uses Cisco equipment as its edge routers.

The configuration commands in this chapter are Cisco IOS commands. (For more information about Cisco IOS syntax, see the Cisco IOS Software Documentation section under Technical Documents at http://www.cisco.com.)
