as regards urpf on the sup720 / rsp720: ipv4, yes; ipv6, no.

BTW, it's worth asking this question when purchasing new equipment: "does 
the equipment support both loose and strict ipv6 urpf in hardware right 
now.  if not, what is the timescale for implementation of each?".

The results are currently not very good.

Vendors: please note that support for ipv6 urpf (both strict and loose) is 
a basic networking requirement these days.
