SRv6 uSID support in SONiC
At the SONiC Summit in the Open Source Summit Europe 2024, Ahmed Abdelsalam of Cisco Systems presented “SRv6 uSID Support in SONiC.”
SRv6 uSID provides a unified solution to deliver any kind of service (VPN, TE, FRR, NFV) end-to-end across the various network segments (Core, Metro, DC, NFV, Cloud, Host). It leverages the IPv6 dataplane to deliver services without the need for any shim layer.
SRv6 has more than 10 IETF RFCs standardizing the different building blocks of the solution including architecture, dataplane, control plane, operations, and management. It enjoys a very rich ecosystem that includes majority of network vendors, merchant silicon and open source.
SRv6 uSID is supported in SONiC as a collaboration between several OCP/SONiC ecosystem members including Alibaba, Cisco, Broadcom and Intel. The SONiC Routing WG has been created to discuss SRv6 features among other routing features.
At the 4th Networking Open Source Tech Conference in Beijing, the PhoenixWing initiative has been launched with the goal to strengthen the SRv6 support in SONiC. The initiative has been endorsed by the Linux Foundation, Alibaba, Cisco, Broadcom, and Microsoft.
SRv6 uSID in SONIC has been deployed in production at Alibaba.
In this presentation we provide an overview of SRv6 and the support in SAI/SONiC/FRR.
