Hi Xiaohu,

> Firstly, I'm glad to see that your IPv6-BIER draft somehow echoes my previous statement about the similarity between the BIER header and the IPv6 header (see below):

I’m happy for you, but I see that differently.

The IPv6 BIER Prefix is a "Bit Index Forwarding Table" (BIFT) Identifier, similar to how the BIER MPLS label is. The difference between the two is that the MPLS label is local significant, and the BIER prefix is global significant.

Thx,

Ice.
