Explains how local and remote W-LIB SIDs support Layer 2 and Layer 3 services and describes their structure, route processing, platform support, limitations, and configuration.
Segment Routing over IPv6 (SRv6) enables advanced network programmability and service chaining by steering packets through a network based on instructions encoded as IPv6 addresses, known as Segment IDs (SIDs). Modern SRv6 deployments leverage SID lists and SID databases (such as W-LIB) to support flexible and scalable network services, including both Layer 2 and Layer 3 offerings.
SRv6 services can utilize either remote or local SIDs, depending on service requirements and deployment models. The integration with the writable SID Library (W-LIB) further enhances service delivery by efficiently managing SID resources and enabling dynamic service provisioning.
These SRv6 services are supported:
-
L2 and L3 services with remote SIDs from W-LIB
-
L3 services with local SIDs from W-LIB
These capabilities enable operators to deliver versatile and scalable network services using SRv6, leveraging both remote and local SIDs managed by W-LIB.
