Hi! Yes, we cannot specify something that routers unaware of this specification should or shouldn’t do.
I believe that Elwyn’s point is this: *if a router supports this specification* then when would it not advertise the ELC? IOW, the specification only obviously applies to implementations that support it — in that case I would think that if a router supports ELs on all of its interfaces then it would always advertise the ELC, right? Thanks! Alvaro.

So what would you suggest? There are existing implementations that support multipath forwarding entropy using MPLS entropy labels but do not signal that capability in OSPF. We can't have a document that retroactively mandates that they signal it. This wouldn't be backward compatible. How can you possibly see this as a serious issue?
