Hi Tony,

     Thank you very much for your comments on BIER-TE path identifier during IETF 111.

     After some thoughts, I think that a BIER-TE path identifier should consist of sub-domain-id, BFR-ID of ingress node, Tunnel-ID and path number. Tunnel-ID is a 32-bit unsigned number, which is unique within a domain for a tunnel from an ingress to a set of egress nodes. There may be a few paths from the same ingress to the same set of egress nodes. The path number is 8-bit unsigned number which is unique under the same tunnel (from the same ingress to the same set of egress nodes). What is your opinion about this?

Best Regards,
Huaimo
