Dear SPRING,

The authors of SRv6 Network Programming believe that this draft is ready to proceed into WG Last Call.

This draft has been implemented by several vendors in multi-Tbps ASICs and there are several opensource implementations. All these implementations have participated in public interoperability testing (SIGCOMM 2017, EANTC 2019).

More importantly, there have been six public deployments in production networks (Softbank, China Telecom, Iliad, LINE Corporation, China Unicom, CERNET2). These deployments are as per today carrying live traffic from millions of subscribers.

The first revision of this draft was published in March 2017. Since then the draft has remained stable and the only significant change has been the new protocol number for ethernet payloads. This stability has been key for the multiple interoperable implementations.

We believe that the next step for the industry is the closure of this document. As such, we recommend to proceed with this document into a WG Last Call.

Many thanks,
Pablo (on behalf of authors & contributors).
