[c-nsp] ASR 9000 Series MPLS Label Limits

Hi All,

I can't find any official Cisco documentation on MPLS label limits in
TCAM in the ASR9000 series routers (ASR9001/RSP440/RSP880 etc).

Are these boxes sharing space with the IP space? So the ASR9001 can
scale to 4M IPv4 prefixes, does that mean it will scale to 2M IPv4
prefixes if every prefix has a label (2M prefixes + 2M labels) ?

Hoping someone might know to save me opening a slow P4 TAC case.
