Calculating VLSM Networks
The following procedure shows how to further subnet 172.16.32.0/20 to 172.16.32.0/26
Step1 Wirte 172.16.32.0 in binary form.
Step2 Draw a vertical line between the 20th and 21st bits. (/20 waas the original subnet boundary)
Step3 Draw a vertical line between the 26th and 27th bits. (The original /20 subnet boundary is extended six bits to the right, becoming /26.)
Step4 Calculate the 64 subnet addresses using the bits between the two vertical lines, form lowest to highest in value.
Route Summarization with VLSM
To determine the summary route, the router determines the number of highest-order bits that match in all the addresses.
