Is this right? It seems very wasteful, given that in the IPv4 world I only have labels for my IGP routes and everything else is happy being sent towards their favourite default route with just a "loopback" label on it.
Sure, but that's labelled v4. 6PE is not just a straight translation of the same concepts because the labels are advertised in BGP to permit a v6-free, MPLS-only core.
Some of the Cisco documentation mentions an "aggregate" IPv6 label, which would make more sense. Is this available on 7600/6500?
I believe so, though I can't remember the command off the top of my head. However, be aware that aggregate labels require recirculation, so halve your max PPS IIRC? Bit hazy on that last bit.
