Please could you clarify whether this document is being reviewed by the 
MPLS WG as part of this process?

Please can you explain how the entropy system works in MPLS?

Are you expecting the P router to look into the BIER header, or are you 
expecting BIER capable nodes to construct an entropy structure in the 
outer label stack.

If the latter, you have two methods available to you the EL system, and 
the FAT PW system. The former is becoming the method of choice where 
available, but you have the option of using the later which will work in 
any network.

I find the title a little strange since the union of MPLS and non-MPLS 
is all networks and thus you ought to cut the title after "Replication".

Best regards

Stewart
