While I never concluded the discussion (until now), but there is very little support for the requirement from operators. The flooding reflector draft did have the most support with support from one operator who was not a co-author on the draft. We could move these presentations to the second ses

Hi Peter, As described in the abstract, the purpose of this draft is to define a simplified control plane mechanism to build SR based Virtual Transport Network (VTN), it is based on the combination of IS-IS Multi-Topology with other IS-IS extensions, e.g. the extensions for TE, SR and L2 bundl
