What is SRv6?

SRv6 (Segment Routing over IPv6) is a next-generation network routing technology that leverages the IPv6 data plane to forward packets along a specified path. It is commonly used to simplify network operations, enhance network programmability, and enable advanced traffic engineering capabilities. It achieves this by encoding forwarding instructions within the IPv6 header, eliminating the need for intermediate node state and reducing the complexity of traditional MPLS-based networks.

MPLS

MPLS is an alternative data plane technology to SRv6. While SRv6 uses IPv6 headers for forwarding, MPLS uses labels. They both aim to provide traffic engineering and VPN services, but in different ways.
