Hi Group,

From carriers' point view, the application scenario for the Generalize SRv6 SID is valid. It can provide some important functions as follows.
1.  In the process of network evolution, there are cases where IPv6 networks and IPv4 networks coexist. An SRv6 packet may cross IPv4 networking. Usually, the packet will be transported by an IPv6 over IPv4 tunnel.G-SID provides two options for carrying IPv4 tunnel information.
2. In the SD-WAN scenario,  An SRv6 packet may cross the MPLS domain. The Generalized Segment Routing Header can effectively reduce the configuration in the middle nodes.

Best Regards,
Cong Li

Hi Folks,
We proposed following two drafts. They are to propose the unified mechanism based on Generalize SRv6 SID 
which can encapsulate Compressed SRv6 SID, MPLS Label and IPv4 tunnel information to cope with the 
emerging new requirements of SRv6 including SRv6 compression, crossing SR-MPLS domains and crossing 
IPv4 domains. At the same time the mechanisms keep the compatibility of the existing SRv6 Network Program 
mechanisms and comply with the basic rule of Segment Routing that the path is programmed in the ingress node 
without introducing extra network states in the transit nodes.

Abstract:
   As the deployment of SRv6, some new requirements are proposed, such
   as SRv6 compression, transporting over SR-MPLS/MPLS and IPv4 domains.
   Therefore, it is necessary to consider other types of segments or
   sub-paths in the end-to-end SRv6 network programming.

   This document proposes Generalized Segment Routing over IPv6 (G-SRv6)
   Networking Programming, which supports to encode multiple types of
   Segments in a SRH, called Generalized SRH (G-SRH).  These Segments
   can be called Generalized Segment, and the ID can be Generalized
   Segment Identifier (G-SID), which may include an SRv6 SID(128 bits),
   C-SIDs, MPLS labels, or IPv4 tunnel information.

   This document also defines the mechanisms of Generalized SRv6
   Networking Programming and the requirements of related protocol
   extensions of control plane and data plane.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
