Hi Tony,
Thanks for your quick reply. For the scenario as you mentioned, wouldn't the non-MPLS-BIER-over-UDP encapsulation (https://tools.ietf.org/html/draft-xu-bier-non-mpls-encap-over-udp-02.txt) be good enough? 
Best regards,Xiaohu

I think the draft explains it. This mechanism does not precondition any kind of specialized BIER HW support (i.e. ether chip with programmable ether types or MPLS silicon). This may be good enough for e.g. HomeNet deployment ...

I'm a bit confused about the motivation of the following BIER-IN-IPV6 mechanism. If it's targeted for the hop-by-hop forwarding paradigm, wouldn't the non-MPLS -BIER encapsulation (over Ethernet) be good enough?

Ad> Can we say “in co-operation with IETF WGs chartered with IGP protocol ownership”  instead of “in cooperation
 with the LSR WG”. DO not want to re-charter in case we change/modify/merge/evolve other WGs.

The BIER-WG is additionally chartered to start Standards Track work on:

  7) BIER in IPv6 :  A mechanism to use BIER natively in IPv6 may be

     standardized if coordinated with the 6MAN WG and with understood

     applicability.  Such functionality may focus on assuming software or

     slow-path support first.Ad> I do not think we should limit unnecessarily the solution or open doors for things that are possible (anything can be done in S/W) but potentially of little value.
 SO if someone brings a proposal for slow-path BIER we will evaluate on usefulness to use case being solved.
