Hi, I support the seperation of address mapping from tunneled or translated 4rd mechanisms. I have some comments as below. 1. Is there any reason you changed 4rd BR to 4rd AFTR? 2. Is 4rd IID for differentiate native ipv6 packets and translated ipv6 packets? In other words, tunneled 4rd don't need that. 3. For the ICMPv4 containing the copy of error packets, i think BR/AFTR or CPE can do forwarding based on the copy of error packets unless the copy didn't cover the complete TCP/UDP header. For ICMP echo request, you should say the ID field should be within the port set range. All these topics are in section 5.1. 4. why omit ipv6 suffix in figure 1? 5.don't get why you pad 0 to ipv6 suffix in figure 2? 6. in the paragraphy just below figure 2, shoud you replace 64 with X in the L=min(14, 64 ...? BTW, it seems to me, the PSID to port sets mapping is different from draft-murakami-softwire-4rd-00. 7. in example a in section 6, how come a mapping rule responding to 2 cpe ipv6 prefix length? cpe will get confused when it did forwarding.
