Hi,

Resending this because I am hearing silence and that could mean:
- no one cares
- no one read the original email

Subject: [mpls] A question about draft-ietf-mpls-sfl-control

Hi WG,

While talking about draft-ietf-mpls-rfc6374-sfl and
draft-ietf-mpls-sfl-control with Stewart, and resulting from SEC ART review
of draft-ietf-mpls-sfl-control by Charlie Kaufman, we discovered that there
is a small hole in the control protocol arising in MP2P LSPs when one of the
senders crashes and restarts.

There are two possible approaches to solving this:
1. introduce a protocol fix
2. scope the utility of the control protocol draft to p2p and p2mp only

But, before going there, we are interested to know whether anyone cares
about this control protocol. Has anyone implemented it? Does anyone plan to
implement it?

Thanks for any answers.

Adrian
