About the technology
Routing core
IS-IS is a link-state routing protocol used to carry reachability information across large IP networks. Companies bring in specialists to design stable backbone routing, clean up area layouts, and improve convergence when the network must stay predictable under load.
Where it fits
It is common in service-provider, carrier, and large enterprise backbones where resilience matters more than simple setup. IS-IS is also used in modern IPv4 and IPv6 designs, especially when teams want a protocol that scales cleanly across routed cores and edge domains.
Typical work
- Build or refactor IS-IS area design
- Configure adjacencies, metrics, and route policies
- Support migration from OSPF or mixed routing designs
- Troubleshoot convergence, leaks, and adjacency flaps
- Validate dual-stack routing behavior
Tooling and ecosystem
Strong specialists know how IS-IS behaves on Cisco, Juniper, Nokia, Arista, and similar network stacks. They work with routing policy, interface design, telemetry, packet captures, and lab tests to verify how the protocol behaves before changes go live.
When to bring in help
Companies often need freelance expertise during backbone redesigns, M&A network integration, migration projects, or incident recovery. In Germany, this is especially useful when local teams need short-term support for critical changes while keeping production coordination in English or German.
What strong experts do
Good IS-IS professionals do more than memorize commands. They understand SPF behavior, metric strategy, route redistribution, authentication, and how to keep routing simple enough for operations teams to maintain. They document clearly and test changes against failure scenarios before rollout.
Frequently asked questions
Everything clients usually want to know about IS-IS, in one place.
IS-IS is used for internal routing in large IP networks, especially backbones that need stable convergence and clear topology control. It is a common choice for service-provider and carrier environments, but it also appears in large enterprise cores and dual-stack designs.
IS-IS and OSPF are both link-state routing protocols, so they solve similar problems. IS-IS is often preferred in very large or highly structured backbones because of its area model and operational style, while OSPF is more familiar to many teams. The better choice depends on the existing network, tooling, and operations practice.
A strong IS-IS specialist should understand routing policy, SPF behavior, metrics, route redistribution, and adjacency troubleshooting. Experience with IPv6, network automation, packet analysis, and vendor-specific routing stacks is also valuable because IS-IS work usually touches the wider routing domain.
Projects that change the backbone usually need IS-IS expertise most. That includes migrations from another routing protocol, area redesigns, network expansion, incident recovery, and dual-stack rollouts. The more critical the core network, the more important careful testing and documentation become.
IS-IS work can often be done remotely if the specialist has good access to lab systems, monitoring, and change windows. On-site support becomes useful during major cutovers, hands-on troubleshooting, or when a company wants close coordination with network operations. In Germany, mixed remote and on-site collaboration is common.
Look for someone who has designed and operated IS-IS in production, not just configured it in a lab. Good signs are clear change plans, solid failure analysis, vendor depth, and the ability to explain why a topology choice is safe. Strong specialists also write documentation that operations teams can actually use.
Yes, IS-IS is still very relevant for modern IPv6 backbones. Many teams value it because it adapts well to dual-stack routing and large routed cores without forcing unnecessary complexity. It remains a practical choice where predictable operations matter more than trend-driven design.
The most common IS-IS problems are adjacency issues, bad metric design, route leaks, and unclear redistribution rules. Another frequent issue is weak documentation, which makes later troubleshooting much harder. A good freelancer will test these paths before rollout and leave the network easier to run.
The average hourly rate of freelancers in Germany who have used IS-IS in their recent projects is 99 €, which corresponds to a daily rate of about 790 € based on an 8-hour working day.
Of the freelancers in Germany who have used IS-IS in their recent projects, 60% hold at least a Bachelor's degree and 20% hold at least a Master's degree.
On average, freelancers in Germany who have used IS-IS in their recent projects have 26 years of professional experience, with a single engagement typically lasting around 2.4 years.
