Not sure I understand the context for your requirement.
But to the best of my understanding your requirement does not match MPLS architecture.

Subject: [spring] [SPRING] Query related to SR Architecture


We would like to have a label stack with only two labels such a way that service label is a top label  and the bottom label would be SR destination node label. This is to make sure each intermediate node perform the specified service based on the top label while reaching the destination.
We would appreciate if anyone could clarify whether SR architecture could allow a service label to be a top label in a label stack.

Thanks and Regards,
Gaurav Agrawal
