Definitive Segment Routing for engineers

Description

Definitive Segment Routing course description

This Segment Routing (SR) training course is a comprehensive program designed to equip network professionals with the knowledge and skills needed to implement and manage SR in modern networking environments. Segment Routing is a cutting-edge network architecture that enhances network flexibility, scalability, and efficiency. This course offers in-depth coverage of SR principles, protocols, and practical implementation techniques. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.

What will you learn

• Explain packet paths when implementing SLB.
• Explain how Segment Routing works.
• Explain the relationship between SR and MPLS.
• Use SR for Traffic Engineering.
• Troubleshoot Segment Routing.
• Implement TI-LFA using Segment Routing
