A follow up related question is let’s say you have a 100% migrated to SR-MPLS and so any mLDP related PSMI UI/MI/S trees are not possible but you can still I guess use IR or RSVP-TE.
You don’t want to use RSVP-TE and don’t want to use IR due to processing replication overhead. But if Tree SID instantiation only works with controller based model and you have a distributed model deployment what options do you have and is their any way you can use Tree SID instantiation using SR-TE with binding SID.
