Re: [mpls] Working Group Last Call : draft-ietf-mpls-lsp-ping-registries-update-04

Shraddha,

I have been waiting for that question. The reason I did not change to FCFS is that there are only four “private use” code points. If you make them FCFS there is a risk that they will be used up very quickly. IANA documents the allocation of FCFS code points, so as soon as the fourth code is allocated, they are gone. 

This is true for Message Types, Reply Modes and Return Codes. 

In all fairness I did not think keeping them “private use” was ideal, but it was the least harmful alternative I could find.
