Couple thoughts.

1. The current draft doesn't specify the static mapping rule like what 4rd
does. So I guess we can't compare this to 4rd.

2. I keep thinking what are the difference of this and PRR. I guess
Qiong's PRR definition is the forwarding decision would be done in the
FIB. I don't disagree with this. My argument is the AFTR will need to use
the port-range to find out the next-hop (the b4's IPv6 address). The
difference between this and the PRR is the information is stored in the
NAT table rather than the routing table. But the general idea is the same.
