Hi Co-authors,

Another question:

If we want to support VNI aware bundling EVPN, VN ID should be carried in the MPLS encapsulated frames. There carrying method can be:

1. Using extra MPLS Label to carry VN ID. But MPLS Label has only 20 bits, it doesn't match 24bits VN ID.

2. Using Ethernet Tag to carry VN ID. VLAN ID has only 12 bits, it also doesn't match 24bits VN ID.

Do you have any other carrying VN ID method? What's your suggestions?

Thanks

Hi Co-authors,
I have read the draft, it provides an applicable solution for VXLAN/NVGRE network interconnection.
But some details haven't been clearly described, so i have the following questions:
1. How to allocate ESI Label in this scenario?
2. How to achieve mass MAC withdraw/Alias when local network occurs topology change?

If you have considered this question, clarifications are appreciated. If you haven't considered, we can work together for these points.
Thanks
