Re-,
Since the "rules" are "maintained" in different ways, then the
forwarding behaviors, for incoming traffics and CE-CE etc., are
different, IMHO.

So the only difference between 4rd BR and lightweight AFTR is just a
static mapping rule for all users in the same domain (4rd BR case) and
group rule or user specific rule for different users (LW AFTR)?

hi,
If I understand it correctly, a per user address/port mapping table is
maintained on the LW AFTR, then no session table on it.

I see your point. So what is the difference between a lightweight

In our consideration, lightweight AFTR is not doing port-range
routing. In this lightweight AFTR, it would firstly lookup a mapping
table (recording [IPv6 address, IPv4 address, Port set]) for a
downstream IPv4 packet. Then after IPv4 packet has been encapsulated
into IPv6 packet, it will do IPv6 routing based on different IPv6
addresses. So, lightweight AFTR does not need to distribute port-set
info into FIB and there is no impact on existing routing architecture
between B4 and AFTR.
