About the technology
Routing Core
IS-IS, short for Intermediate System to Intermediate System, is a link-state routing protocol used to move traffic across large Layer 3 networks. It is common in service provider backbones and in enterprise cores that need stable, scalable routing with clear area design. Strong experts know how to keep adjacency, SPF behavior, and route propagation predictable.
Typical Work
- Design Level 1, Level 2, and multi-area routing
- Build backbone and edge routing for MPLS and IP networks
- Tune metrics, summarization, and route preference
- Troubleshoot adjacencies, flaps, and convergence issues
- Prepare migration plans from OSPF or older designs
Tooling And Standards
Work usually spans Cisco IOS and IOS XE, Juniper Junos, Nokia SR OS, and other carrier-grade stacks. Experts also deal with BFD, MPLS, IPv6, traffic engineering, and route policies around IS-IS. They should read packet captures, review SPF timing, and validate topology changes before rollout.
When To Bring In Help
Companies often bring in freelance IS-IS specialists during backbone changes, incident recovery, audits, or platform migrations. In Germany, this is common when teams need short-term support for cross-site networks, carrier handoffs, or multilingual documentation that must stay precise. Remote work fits design and troubleshooting well, while on-site time helps during cutovers.
What Good Looks Like
Strong professionals do more than configure neighbors. They understand topology, failure domains, and how IS-IS behaves under load or during partial outages.
- Clear network design and clean area boundaries
- Practical troubleshooting across control plane and data plane
- Safe change plans with rollback steps
- Familiarity with vendor differences and route policy details
Related Skills
IS-IS work often sits next to MPLS, IPv6, BGP, BFD, QoS, and automation with Ansible or similar tooling. The best specialists can explain why a route is preferred, how an LSP change affects the network, and where to place filters without breaking reachability. That mix matters when the network must stay stable during growth or migration.
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 clean hierarchy. It carries reachability between routers and helps operators control how traffic moves through the core. You will most often see it in service provider networks and large enterprise cores.
IS-IS is not universally better; it is a different fit. Teams often choose it for large, well-structured core networks because the protocol scales cleanly and keeps the design simple at the area level. OSPF is also common, so the right choice depends on the existing network, vendor stack, and operating model.
A strong IS-IS specialist usually understands BGP, MPLS, IPv6, BFD, and route policy. Those skills matter because IS-IS rarely lives alone in a modern backbone. Experience with Cisco, Juniper, or Nokia platforms is also valuable when the network spans multiple vendors.
A IS-IS project can be simple if it is a small lab or a limited change, but production backbones need proven hands. The right specialist should have handled adjacency issues, area design, and safe migration work before. For cutovers or incident recovery, practical network operations experience matters more than theory.
Yes, much of IS-IS design, troubleshooting, and documentation can be done remotely if the team has good access to the network and clear change control. On-site support can help during hardware swaps, major cutovers, or when hands-on coordination is needed. In Germany, many teams combine remote planning with short on-site sessions.
Look for clear explanations of areas, metrics, SPF behavior, and failure handling in IS-IS. Good specialists can describe how they would prevent route leaks, reduce flap impact, and validate a change before rollout. They should also be comfortable reading logs, topology outputs, and packet captures.
IS-IS is the common name people use today, while ISO IS-IS refers to its original ISO network layer roots. In practice, most hiring conversations mean the IP routing protocol used in modern networks. If a candidate can explain both the history and the current deployment model, that is usually a good sign.
IS-IS is most common in carrier networks, large backbones, and some enterprise cores. Location matters when you need on-site support for cutovers, hardware work, or close coordination with local teams, but many design and troubleshooting tasks can be handled remotely. For Germany-based projects, clear communication and exact documentation are especially useful.
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.
