Part of the Cisco® 1000 Series Integrated Services Routers (ISR), the ISR 1100-4G, ISR1100-4GLTE and ISR 1100-6G models are powered by the Viptela® operating system and combine WAN and comprehensive security in a wired high-performance platform. The ISR 1100-4G, 1100-4GLTE and 1100-6G combine an enterprise grade platform with best-in-class SD-WAN.

Cisco Software-Defined WAN (SD-WAN) is a cloud-first architecture that provides unparalleled visibility across your WAN, optimal connectivity for end users, and the most comprehensive security platform to protect your network. Cisco SD-WAN provides transport independence, rich network, and security services as well as endpoint flexibility.

The ISR 1100-4G, 1100-6G and 1100-4GLTE routers are delivered as platforms that sit at the perimeter of a site, such as a remote office, branch office, campus, or data center. They participate in establishing a secure virtual overlay network over a mix of any WAN transports.

Business need


Lightweight, compact size with low power consumption

  Can be deployed in many different environments where space, heat dissipation, and low power consumption are critical factors

High performance to run concurrent services

  High performance allows customers to take advantage of broadband network speeds while running secure, concurrent data, voice, video, and wireless services

High availability and business continuity

  Redundant WAN connections for failover protection and load balancing
  Dynamic failover protocols such as Virtual Router Redundancy Protocol (VRRP; RFC 2338)

Consistent, high application performance levels

  The router can run multiple services simultaneously with minimal performance degradation.
  Cisco SD-WAN delivers the best user experience over any connection.
