  1. TRILL OAM use of CFM TissaSenevirathne (Cisco) tsenevir@cisco.com new-senevirathne-trill-oam-liaison-0114-v01

  2. Common OAM architecture and protocol suite between SDOs • Not limited to TRILL, but potential use in other overlay protocols • Single toolkit for customers • Savings in training • Savings in OPEX (more efficient troubleshooting) • Increase CFM footprint to areas that it has not been widely used so far • Reduced R&D time and hence faster time to market Motivation new-senevirathne-trill-oam-liaison-0114-v01
