Kickstart your journey to IPv6 with Phase Routing over IPv6 (SRv6)

Phase Routing over IPv6 (SRv6) is an extension of the IPv6 structure that permits the insertion of routing directions, generally known as segments, immediately into IPv6 headers. This standards-based know-how 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 checklist of segments. The checklist of segments instructs nodes on methods to course of a packet. As the trail info is inside a packet transit or intermediate nodes should not 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 commonplace for the US Federal Authorities. IP Model 6 offers the extra addressing and basis in the direction of a Zero Belief enabled infrastructure.  

Combining Phase Routing with IPv6, generally known as Phase Routing over IPv6 (SRv6), lays the inspiration for end-to-end companies and 0 belief safety throughout a complete group/enterprise.  

Why Phase Routing 

Phase routing simplifies community structure and operations through source-based routing. On the information aircraft Phase Routing can run through IPv6 or through multiprotocol label switching (MPLS). With the OMB IPv6-Solely mandate and the inherent advantages of SRv6, authorities organizations ought to 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 aircraft complexity facilitates organizational visibility, operational simplicity, and infrastructure administration. Merely put, when you can troubleshoot IP, you’ll be able to troubleshoot SRv6. In an IPv6-Solely atmosphere SRv6 permits organizations to seamlessly scale and achieve (again) the 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 through 1 easy prefix. Enterprises and enormous organizations with tens of hundreds 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 transport of SRv6 since 2019. Moreover, SRv6 is integrated inside open-source tasks and open-source communities. Going ahead it will 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 embrace the Quick Information Mission FD.io, SAI/SONiC, and Free-Vary Routing (FRR).

Public Sector and Enterprise Use Instances   

SRv6 together with IPv6-Solely is relevant wherever inside a corporation. Throughout authorities and public entities this contains regional schooling networks, broadband and center mile initiatives, healthcare (e.g., telemedicine), 5G, Personal 5G, IoT, and Edge. Future use-cases are quite a few with advantages past legacy infrastructure; to incorporate extension of SRv6 companies to the applying layer.  

 A superb high-level design (HLD) of SRv6 could be discovered right here: Cisco Converged SDN Transport SRv6 Excessive Stage Design. The ideas inside this HLD reminiscent of a core community are the identical as a self-managed broad space community or core community of a big enterprise. In referencing the Cisco IPv6 Journey Map , public sector organizations ought to think about and plan for SRv6 inside the technique/planning section. The final word consequence of transition to SRv6 and IPv6-only being mission success with added advantage of alignment with the OMB Mandate.
