TRILL OAM use of CFM Tissa Senevirathne (Cisco) tsenevir@cisco.com new-senevirathne-trill-oam- liaison-0114-v01 1/17/14 1
Motivation 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 new-senevirathne-trill-oam- liaison-0114-v01 1/17/14 2
Nested MP Interaction 802.1 device TRILL device 802.1 device TRILL device TRILL device MD Level 0 7 802.1 customer MD Levels TRILL MD Level 0 7 MD Level 0 7 Link MD Levels MEP for TRILL RBridge MIP for 802.1 bridge new-senevirathne-trill-oam- liaison-0114-v01 MEP for 802.1 bridge MIP for TRILL RBridge 1/17/14 3
