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.

Comparison of Models

Cisco 3250 Mobile Access Router

• Targeted at Military and Command & Control

Environments in public safety

• Can provide higher density of Serial and/or Fast

Ethernet ports than the Cisco 3220 model

• Choices for conﬁguration of Mobile Interface Cards

• Use of four ports on each SMIC or FESMIC

• Multiple SMICs supported

• Can be upgraded to future interface cards such as

future 802.11 card

• Options for Cisco IOS Software images

• Customers conﬁgure and order one or more SKUs for

MARC, SMIC, FESMIC, and Cisco IOS software

Features and Benefits

The Cisco 3200 Mobile Access Router offers three primary features and beneﬁts, which are detailed as follows (refer

also to Table 1):

• Seamless roaming IP availability, independent of location, movement, or infrastructure

• High performance in a compact, rugged design for use in vehicles or in remote ﬁeld locations

• Advanced IP services and interoperability via Cisco IOS Software Mobile Networks

Cisco 3320 Mobile Access Router

• Targeted at mass deployments in Commercial

Transportation and Public Safety markets

• Pre-conﬁgured model (MARC, 2 Port SMIC, 2 Port

FESMIC)

• Use of two ports on the single FESMIC or SMIC

• No additional FESMICs or SMICs can be added to the

model

• Can be upgraded to future interface cards such as

future 802.11 card

• Cisco IP PLUS image loaded by default (supports

3DES)

• Single SKU for customers to order
