Dual-homed hosts lose 50% of network capacity through the MLAG domain while the switch reboots

The peer switch also reboots to ensure network stability.

The peer switch sends out gratuitous BPDUs to let the network know that it has assumed the root-bridge role.

Nothing bad ever happens when MLAG is enabled!
