Segment Routing (SR-MPLS / SRv6)

Build deep, hands-on expertise across the full Segment Routing landscape, from SR-MPLS fundamentals and IGP integration through traffic engineering, SRv6 network programming, migration strategy, and next-generation VPN and EVPN services. This course gives you practice equivalent to the Segment Routing and SRv6 scope found in the Cisco CCIE Service Provider and SPCOR (350-501) blueprints. Designed for CCIE Service Provider candidates and working service provider engineers who want to build segment routing expertise from first principles through production-grade deployment scenarios.

FAQ

A working knowledge of MPLS fundamentals and at least one IGP (IS-IS or OSPF) is recommended. The course builds from Segment Routing fundamentals through advanced SRv6 and migration scenarios, but prior exposure to traditional MPLS label switching will help you move through the early modules faster.

Both. The course is structured to build SR-MPLS fundamentals and traffic engineering first, then transitions into SRv6 network programming, traffic engineering, and next-generation services, with a dedicated module on migrating between the two.

The majority of each module includes a hands-on lab component built around a shared multi-node topology, so you configure, verify, and troubleshoot each concept directly rather than reading about it.

Yes. The course is aligned to the Segment Routing and SRv6 scope found on the Cisco CCIE Service Provider lab blueprint and the SPCOR (350-501) exam topics.
