Dividing Networks from Networks • There is a direct relationship, bit for bit, between the IP Address and it's associated subnet mask. • Any subnet mask bit that is a 1 means that the associated address bit belongs to the network number. • Any subnet mask bit that is a 0 means that the associated a ...

Moreover, it is also receiver-driven, meaning that a router will request LSAs only when it has CPU cycles. Thus it is less likely a router will be overwhelmed by a flurry of updates. Our ...
