Apply this sequence of commands to the following virtual routers, assigning each a priority of
101:
n VR 2 - Priority 101
n VR 3 - Priority 101
n VR 4 - Priority 101

ing virtual routers:
n VR 2 - Track l4pts VR 6 - Track l4pts
n VR 3 - Track l4pts VR 7 - Track l4pts
n VR 4 - Track l4pts VR 8 - Track l4pts
