Re: [sfc] Fwd: New Version Notification for draft-ietf-sfc-multi-layer-oam-05.txt

Hi Gyan,
thank you for your interest in the SFC OAM work and your thoughtful
suggestion. Indeed, every moving part we introduce in a network must
include a robust security mechanism. We'll work on a solution and hope to
share our proposal with you and the group soon.

Regards,
Greg
