Configuring AAA for Cisco Perimeter Routers
The remainder of this chapter describes how to configure a Cisco perimeter router to perform AAA using a local database.
Authenticating Perimeter Router Access
Following the Cisco SAFE axiom that all routers are targets, it is important that you secure your network access servers and Internet routers at all interfaces.
As Figure 2-15 illustrates, you must configure the perimeter router to secure administrative access and remote LAN network access using AAA commands.

Table 2-2 compares the router access modes, port types, and AAA command elements.
