Re: [mpls] Poll for Adoption draft-andersson-mpls-moving-iana-registries-00

Carlos,

as long as we move them out of the LSP Ping registry and we can find a
place where we have consensus that we should move them, I fine with
that.

Any suggestions?

However, since you are "Moving Generic Associated Channel registries to a new name space", "fix modularly" can mean coalesce all the GACH registries, from LSP Ping as well as from the other 2-3 registries. In other words, fix two (LSP Ping and GACH) with potentially very small additional incremental effort.
