And of course you can tag^H^H^Hlabel switch IPv6 through a non-IPv6-aware
core, it just breaks traceroute (as even if you pop a label off the stack
on TTL expiry, your core still can't understand the resulting packet to
return a TTL expired).

But then, much of said vendor's switching equipment with routing 
functionality doesn't know about MPLS either - just IPv4.
