Home Agent Configuration

Problem

You want to configure a router to act as a Home Agent for Mobile Nodes.

Solution

The first step in configuring IP Mobility in your network is to set up one or more Home Agent routers, which will act as the virtual home base and support tunnels for your roaming devices:
