DETAILED INFORMATION
New Features
Foreign Agent Local Route Optimization
In mobile IP networks, endpoint devices sending traffic through a single foreign agent must traverse through a home agent router. Often the home agent is in a different geographic region. Sending the traffic through a home agent may cause latency and unnecessary traffic across a mobile IP network.
The advantage of foreign agent local route optimization is that the Internet traffic between end devices attached to a foreign agent now can communicate with each other directly using the foreign agent router. Because the foreign agent router is further out in the network, fewer network delays are experienced and traffic is optimized across the mobile IP network.
Zeroization
Zeroization is a feature designed to clear the router of information when the security of a router is jeopardized. The zeroization function clears the router of information such as IP addresses, configuration in memory (NVRAM, Flash memory), and shuts down interfaces. After the zeroization is activated, the router can be redeployed by downloading a new image.
Table 2 lists the 3200 Series Image File Names that support FA Local Route Optimization and Zeroization features.
