Cisco ISR 1100 Router | 4xGE WAN/2xGE LAN/8GB DRAM – Aixia

The Cisco ISR 1100 router is a modular, next-generation branch router. It’s built for businesses that need flexible WAN connectivity, strong performance, and room to grow. As a result, it combines routing, security, and SD-WAN readiness in a compact, enterprise-grade platform.

Interfaces & Connectivity
The ISR 1100 comes with 4x GE WAN ports and 2x GE LAN ports. This gives branch offices multiple uplink options, including dual-ISP setups, MPLS/broadband combinations, or LTE backup. In addition, there are enough LAN ports to directly connect switches and access points. With 8GB DRAM, the router also has ample memory headroom to run advanced features. Therefore, it can handle multiple concurrent services without performance degradation.

Routing & Performance
The ISR 1100 is part of Cisco’s Integrated Services Router (ISR) 1000 series. It supports full enterprise routing protocols, including static, RIP, OSPF, EIGRP, and BGP. Additionally, it’s built on Cisco’s IOS XE platform, giving it a modern software architecture. This means it supports automation, programmability, and centralized management via Cisco DNA Center or Meraki on select models. For full technical specifications.

Security & SD-WAN
The ISR 1100 supports Cisco’s security suite, including firewall and VPN (IPSec) capabilities. Depending on licensing, it also supports SD-WAN via Cisco Viptela. As a result, businesses can intelligently route traffic across multiple WAN links based on performance and cost. This makes it a strong fit for multi-site businesses modernizing their branch network architecture.

Design
The ISR 1100 uses a compact, fanless desktop form factor on most variants. Because of this, it’s well suited to space-constrained branch offices, retail locations, or wiring closets without dedicated cooling infrastructure.

Why Choose the Cisco ISR 1100 Router
Growing businesses and multi-branch operations often need multiple WAN uplinks and strong onboard memory. For these needs, the ISR 1100 is a strong fit. Meanwhile, it avoids the footprint or cost of a full data-center-grade router. Overall, it sits at a compelling price-to-performance point, offering enterprise features typically reserved for larger platforms. Furthermore, Cisco’s long-standing reputation for reliability and support makes it a low-risk choice for standardizing branch network infrastructure.
