Folks,
I am wondering whether this is a migration requirement or a functional requirement.
In the rationale, I think that the author might be thinking about the following scenario:
* An SR domain contains IS-IS levels
* Initially, all levels deploy SR-MPLS
* One at a time, each level migrates from SR-MPLS to SRv6
This rationale would lead us to believe that we are looking at a migration requirement.
However, the following scenario is also possible:
* A greenfield network contains IS-IS levels
* For reasons beyond the scope of this document (e.g., hardware price), it makes sense to deploy SR-MPLS in some levels and SRv6 in others
* No migration is planned
In this scenario, we are looking at a functional requirement.
Ron
