Yes, this is what I remember also. But if you look at the PTX1000, you
don't have that problem from when it went into inception.

Granted, one could say Juniper made the assumption that most MPLS-based
networks would run a BGP-free core, and in theory, there were right.
What they didn't account was that 6PE was one of those "temporary
becomes permanent" situations.

Personally, I've never felt running Netflow on core routers is ideal,
particularly if you are a BGP-free core network, and if your collector
isn't that great at grabbing flow data from MPLS frames.
