My strong preference is Option 2. It simplifies migration and network consolidation usecases. Also it is very relevant in MSDC kind of use cases where a single node can be part of two different topologies running two different SR protocol. Index-management becomes much easier in each of the usecases.

We had some comment in Dallas on difficulties that having common label range shared between protocols could lead to. During discussion in our design team, some point was also raised on routing protocol migrations that may be safer using a per protocol SRGB (so configuration the SRGB at IGP level rather than globally). We would like to hear from the WG about the preference and arguments for both approaches : Approach 1) keep SRGB configuration at top level, and so routing protocols will share the same label space (today proposal) Approach 2) move SRGB configuration to protocols, each routing protocol manages its own label space. Thanks to provide your feedback in order to solve this issue and have a consensus.
