v Note: While the shorter header can enhance performance slightly, routers
from other vendors may not be compatible with this feature.
MPQual
This checkbox allows the router to use echo packets on each of the physical
ports in the bundle to determine whether individual links are up. If one link
in a bundle goes down, the router can divert data away from that port.
v Note: If the primary port goes down, the entire link will go down, even if
MPQual is enabled. If left unchecked, any individual link in the bundle can
bring down the entire multilink. (Parameters for echo packets are configured
in the PPP Options/PPP Link Quality dialog box.)
