Hi Linda, Thanks for proposing this draft.
I think it’s worthwhile for the WG to consider the possibility of deploying BIER in non-MPLS networks (e.g., a data center network where VXLAN/NVGRE is deployed). IMHO, one major reason for those DC operators, especially non-SP DC operators to prefer VXLAN/NVGRE to MPLS-in-UDP/MPLS-in-GRE in their data center networks is that they are unfamiliar with MPLS or dislike MPLS instinctively. Honestly speaking, I couldn’t think of any technical advantage of using VXLAN/NVGRE instead of MPLS-in-UDP/MPLS-in-GRE, especially in the hybrid cloud scenario where it’s much necessary to interconnect the DC VPN with the WAN VPN (i.e., MPLS-based VPN) in a scalable way (i.e., by using inter-AS option B). When deploying BIER in the above networks, those DC operators are familiar with MPLS and advocate MPLS all of a sudden. Doesn’t it sound strange?
