VPLS-MCT PE node protection

VPLS MCT provides protection when one PE node has a failure, including a software or hardware failure, or a power-down event. When the active PE fails in MCT, the standby PE becomes the active PE and all PWs on this node transits into MCT active state.

The following figure shows the BUM packet flow after an MCT PE switch-over event.

Note

VPLS MCT does not support PW link protection.
