Phase Routing over IPv6 (SRv6) is an extension of the IPv6 structure that permits the insertion of routing directions, referred to as segments, at once into IPv6 headers. This standards-based era permits simplicity, flexibility, and safety at scale. The architecture, outlined in RFC 8402, is a supply routing paradigm that permits a node inside of a community to influence site visitors thru a site the use of an ordered listing of segments. The listing of segments instructs nodes on methods to procedure a packet. As the trail data is inside of a packet transit or intermediate nodes should not have to deal with state of the entire paths inside of a community.   

IP Model 6 (IPv6), as famous in IPv6 OMB Mandate: What’s Your Technique? is the brand new IP usual for the United States Federal Govt. IP Model 6 supplies the extra addressing and basis against a 0 Believe enabled infrastructure.  

Combining Phase Routing with IPv6, referred to as Phase Routing over IPv6 (SRv6), lays the root for end-to-end services and products and 0 accept as true with safety throughout a complete group/undertaking.  

Why Phase Routing 

Phase routing simplifies community structure and operations by means of source-based routing. At the information aircraft Phase Routing can run by means of IPv6 or by means of multiprotocol label switching (MPLS). With the OMB IPv6-Simplest mandate and the inherent advantages of SRv6, govt organizations must be gearing against SRv6.  

SRv6 empowers community operators with enhanced site visitors engineering and the facility to head past. SRv6 permits environment friendly and resilient useful resource usage, Any VPN, Provider Serve as Chaining (SFC), 5G habits natively with IPv6, and optimized trail variety. The simplicity received thru diminished keep an eye on aircraft complexity facilitates organizational visibility, operational simplicity, and infrastructure control. Merely put, if you’ll be able to troubleshoot IP, you’ll be able to troubleshoot SRv6. In an IPv6-Simplest setting SRv6 permits organizations to seamlessly scale and acquire (again) the benefits of IP and IPv6 thru deal with summarization. As an example, a site of 10 or 10,000 or higher can also be summarized right into a unmarried IPv6 commercial reachable by means of 1 easy prefix. Enterprises and massive organizations with tens of 1000’s of nodes can now supply complete reachability with only a few IPv6 prefixes.

Cisco has been a pacesetter in Phase Routing and SRv6 since its inception in 2013; to incorporate transport of SRv6 since 2019. Moreover, SRv6 is integrated inside of open-source tasks and open-source communities. Going ahead this may occasionally proceed to power construction and interoperability of SRv6 and be offering advantages with regards to innovation, collaboration, and customization in assembly and exceeding industry and venture targets. Some examples of open-source tasks come with the Rapid Knowledge Undertaking FD.io, SAI/SONiC, and Loose-Vary Routing (FRR).

Public Sector and Endeavor Use Circumstances   

SRv6 in conjunction with IPv6-Simplest is acceptable any place inside of a company. Throughout govt and public entities this comprises regional schooling networks, broadband and heart mile tasks, healthcare (e.g., telemedicine), 5G, Personal 5G, IoT, and Edge. Long run use-cases are a large number of with advantages past legacy infrastructure; to incorporate extension of SRv6 services and products to the applying layer.  

 A very good high-level design (HLD) of SRv6 can also be discovered right here: Cisco Converged SDN Shipping SRv6 Top Stage Design. The ideas inside of this HLD comparable to a core community are the similar as a self-managed broad space community or core community of a giant undertaking. In referencing the Cisco IPv6 Adventure Map , public sector organizations must believe and plan for SRv6 inside the technique/making plans section. Without equal end result of transition to SRv6 and IPv6-only being venture luck with added good thing about alignment with the OMB Mandate.
