1. 2. 3. RB-1 1. 2. 3. 4. RB-2 Utilize Shared addressing model Default MA of any MD- Level include all RB and MEP at the NULL PHY MEP at NULL PHY i. e. CPU) allow to initiate LBM, PT, MT between RB (YELLO W MA) Per Flow MA for end to end CCM, (Flow monitoring). See Green and Blue MIP allow to respond to PT MEP allow to initiate LBM, PT etc PT messages arrives with TTL=0 RB-3 1. Implement Shared Addressing Model 2. i. e. All of the MEP have a single Address 5 5
