Depending on the platform/feature, "any" seems to just map to "1-4095" anyway.

I've tried doing this with EVC's on ASR1k, and it doesn't seem to work.

I've tried doing this with ambiguous subinterfaces on the ASR1k, and it
partially works, but not well enough to be usable.

Talking to a Cisco SE, the ASR9k is apparently the first platform which
properly supports termination of broadband users, using DHCP, as IPoEoQinQ. I'm
just waiting for the loan box to arrive to prove it in the lab.
