Getting routers from different vendors to work together should be simple. They all follow the same standards, so why do routers often struggle to interoperate?

The answer lies in the details. Being “standards-compliant” does not always mean “standards-consistent.”

From mismatched protocol defaults to conflicting MTU settings, small differences in configuration and implementation can lead to major issues. This becomes especially problematic in mission-critical networks such as public safety, financial systems, and transportation infrastructure.

The Real Problem

Even when routers support the same protocols, such as OSPF, BGP, LDP, or Segment Routing, variations in how vendors implement those protocols can break compatibility. Terminology, default behaviors, and optional features often vary, making multivendor network integration complex and error-prone. Interoperability assessment often requires extensive documentation review, multi-vendor testing, and protocol compliance analysis, making it both broad in scope and resource-intensive.

The Aviat Solution

Aviat’s AOS routers are designed for real-world multivendor IP/MPLS environments. They offer:

• Standards-based routing support for OSPF, IS-IS, MP-BGP, LDP, and Segment Routing
• Proven interoperability with Cisco, Juniper, Nokia, and other leading vendors
• Configuration templates for both external peering and internal phased upgrade scenarios

Router interoperability challenges and complexities can be managed by adopting a testing methodology that organizes tasks by application, scenario, requirements, and networking layer hierarchy.

Whether you are connecting separate networks or upgrading legacy infrastructure, Aviat helps ensure seamless communication between platforms without unnecessary complexity.
