Multi-Chassis LAG
This section describes the Multi-Chassis LAG (MC-LAG) concept. MC-LAG is an extension of a
LAG concept that provides node-level redundancy in addition to link-level redundancy provided
by “regular LAG”.
Typically, MC-LAG is deployed in a network-wide scenario providing redundant connection
between different end points. The whole scenario is then built by combination of different
mechanisms (for example, MC-LAG and redundant pseudowire to provide e2e redundant p2p
connection or dual homing of DSLAMs in Layer 2/3 TPSDA).
