Hi Ice,

In fact, you could look the combination of <BSL, Sub-domain, SI> within the generic BIER header as "Bit Index Forwarding Table" (BIFT) Identifier as well if you would like. BTW, that is globally significant as well:)

Best regards,
Xiaohu

Hi Xiaohu,

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.
