Phase Routing over IPv6 (SRv6) is an extension of the IPv6 structure that allows the insertion of routing directions, referred to as segments, immediately into IPv6 headers. This standards-based expertise permits simplicity, flexibility, and safety at scale. The architecture, outlined in RFC 8402, is a supply routing paradigm that permits a node inside a community to steer visitors by means of a site utilizing an ordered record of segments. The record of segments instructs nodes on the way to course of a packet. As the trail data is inside a packet transit or intermediate nodes don’t have to keep state of all of the paths inside a community.
IP Model 6 (IPv6), as famous in IPv6 OMB Mandate: What’s Your Technique? is the brand new IP customary for the US Federal Authorities. IP Model 6 gives the extra addressing and basis in the direction of a Zero Belief enabled infrastructure.
Combining Phase Routing with IPv6, referred to as Phase Routing over IPv6 (SRv6), lays the inspiration for end-to-end companies and 0 belief safety throughout a whole group/enterprise.
Why Phase Routing
Phase routing simplifies community structure and operations by way of source-based routing. On the information airplane Phase Routing can run by way of IPv6 or by way of multiprotocol label switching (MPLS). With the OMB IPv6-Solely mandate and the inherent advantages of SRv6, authorities organizations must be gearing in the direction of SRv6.
SRv6 empowers community operators with enhanced visitors engineering and the flexibility to transcend. SRv6 permits environment friendly and resilient useful resource utilization, Any VPN, Service Operate Chaining (SFC), 5G conduct natively with IPv6, and optimized path choice. The simplicity gained by means of lowered management airplane complexity facilitates organizational visibility, operational simplicity, and infrastructure administration. Merely put, when you can troubleshoot IP, you possibly can troubleshoot SRv6. In an IPv6-Solely setting SRv6 permits organizations to seamlessly scale and acquire (again) some great benefits of IP and IPv6 by means of tackle summarization. For instance, a site of 10 or 10,000 or bigger could be summarized right into a single IPv6 commercial reachable by way of 1 easy prefix. Enterprises and enormous organizations with tens of 1000’s of nodes can now present full reachability with only a few IPv6 prefixes.

Cisco has been a frontrunner in Phase Routing and SRv6 since its inception in 2013; to incorporate delivery of SRv6 since 2019. Moreover, SRv6 is integrated inside open-source tasks and open-source communities. Going ahead this can proceed to drive improvement and interoperability of SRv6 and supply advantages when it comes to innovation, collaboration, and customization in assembly and exceeding enterprise and mission goals. Some examples of open-source tasks embody the Quick Knowledge Undertaking FD.io, SAI/SONiC, and Free-Vary Routing (FRR).

Public Sector and Enterprise Use Instances
SRv6 together with IPv6-Solely is relevant anyplace inside a company. Throughout authorities and public entities this contains regional training networks, broadband and center mile initiatives, healthcare (e.g., telemedicine), 5G, Non-public 5G, IoT, and Edge. Future use-cases are quite a few with advantages past legacy infrastructure; to incorporate extension of SRv6 companies to the appliance layer.
A superb high-level design (HLD) of SRv6 could be discovered right here: Cisco Converged SDN Transport SRv6 Excessive Degree Design. The ideas inside this HLD resembling a core community are the identical as a self-managed vast space community or core community of a giant enterprise. In referencing the Cisco IPv6 Journey Map , public sector organizations ought to think about and plan for SRv6 throughout the technique/planning section. The last word consequence of transition to SRv6 and IPv6-only being mission success with added advantage of alignment with the OMB Mandate.
