MX Series Virtual Chassis support for multichassis link aggregation

MX Series Virtual Chassis supports configuration of multichassis link aggregation (MC-LAG). MC-LAG enables a device to form a logical link aggregation group interface with two or more other devices. The MC-LAG devices use the Inter-Chassis Communication Protocol (ICCP) to exchange control information between two MC-LAG network devices. When you configure MC-LAG with an MX Series Virtual Chassis, the link aggregation group spans links to two Virtual Chassis configurations. Each Virtual Chassis consists of two MX Series member routers that form a logical system managed as a single network element. ICCP exchanges control information between the global primary router (VC-P) of the first Virtual Chassis and the VC-P of the second Virtual Chassis.
