all participating PEs. The combination of active and stand-by states across LAG links as well and
pseudo-wires give only 1 unique path between pair of MSANs.
Note that the configuration in Figure 26 depicts one particular configuration of VLL connections
based on MC-LAG, particularly the VLL connection where two ends (SAPs) are on two different
redundant-pairs. In addition to this, other configurations are possible, such as:
• Both ends of the same VLL connections are local to the same redundant-pair.
• One end VLL endpoint is on a redundant-pair the other on single (local or remote) node.
