We determine the mask same for all subnets or different masks for single segments as necessary (VLSM). determine subnet addresses for all segments. 3. The process of manual summarization for VLSM subnets. This text talks about how to work out summary routes manually for subnets that don’t. lenge is that a subnetting design that uses VLSM requires more math, and it requires . classless routing protocols support VLSM, but they also support manual.

Well, with traditional subnetting, all subnets must be the same size. The subnet which needs hosts has to have a subnet mask of The subnet which has hosts would still have a subnet mask of Show the subnet eh used.
