The Mobile IP standard (IETF Standard-RFC 2002) within Cisco IOS Software provides the roaming architecture
that allows a Cisco 3200 Mobile Access Router to connect to its home network. Traditional mobile IP allows client
devices such as a laptop computer or personal digital assistant (PDA) to maintain a single IP address and roam among
multiple networks without losing their connection to the home network. Mobile IP is a network layer functionality,
eliminating the need to rewrite traditional applications.
The Cisco IOS Mobile Network feature allows mobile networks to scale, providing mobility management across the
network. Cisco IOS Mobile Network is an enhanced, standards-based implementation of the Mobile IP standard that
transforms a Cisco 3200 Mobile Access Router from a mobile IP node into a mobile IP router. All client devices
connected to the mobile access router can use the router IP addresses for mobility. The router and its subnets maintain
IP connectivity while the vehicle is in motion. Cisco IOS Mobile Network functionality makes connectivity
transparent to all hosts connecting through the router, because client devices connected to the router require no client
software. With Cisco IOS Mobile Network, mobility is scalable and easier to deploy and manage, and it requires
fewer IP addresses.
A key requirement in both military and public safety deployments is secure communications. Cisco IOS Software
includes a robust set of security features for identity management and confidentiality. Users authenticate themselves
to RADIUS-based identity management servers. Powerful, software-based encryption protects communications from
interception or spoofing. An integrated firewall provides stateful protection. Hardware encryption devices may also
be added externally through the available Ethernet ports on the MARC or FESMIC.
