Hi folks,

I found some of the interesting discussion and drafts about BIER IPv6 encapsulation in the mail-list. 

(1) encap BIER information in IPv6 128-bit addresses. 
(2) encap BIER header and BIER payload as IPv6 payload for slow path processing. 
(3) encap BIER header in some IPv6 extension header. 

When the first method was discussed in Sep 2016, there was a suggestion to provide a method of using IPv6 extension header for comparison. Well I think this draft provided one...
https://www.ietf.org/mail-archive/web/bier/current/msg00986.html

Again there were some 'requirements' mentioned by this thread, and this draft seemed to match them well...
https://www.ietf.org/mail-archive/web/bier/current/msg00991.html

"it shouldn't require hop-by-hop modification of the IP destination address field, and it shouldn't require the BFRs to inspect layer 4, and it shouldn't require changes to layer 4, and it shouldn't allow a multicast address to be put in the IP source address field, and it shouldn't assume that bits never get set incorrectly, and it shouldn't require changes in source address filtering procedures. In addition, it should be possible to use it to support the entire BIER architecture"

Comments and discussions are very welcomed.

Thanks
