PBB using G.8031 Protected Ethernet Tunnels

The following displays PBB configuration examples:

Ethernet links on BEB1:

BEB1 to BEB1 L1:

BEB1 to BCB1 L1: 1/1/1 – Member port of LAG-emulation ET1, terminate ET3

BEB1 to BCB1 L2: 2/1/1 – Member port of LAG-emulation ET1

BEB1 to BCB1 L3: 3/1/1 – Member port of LAG-emulation ET1

BEB1 to BCB2: 4/1/1 – terminate ET3
