I promise I will not be a knowledge leech, I will contribute what I know as well. Ofcourse I do have a question regarding IP Summaization: Up untill today I thought I had summarization down cold until I tried a few self made excercises. The formula I used to gather a summ address was 2n=x. Thats 2 to the n power equals x. x is the number of subnets that you want to summarize and n will be how much you subtract from the lowest mask of those subnets. for example:
216.52.146.136/30 216.52.146.140/30 216.52.146.144/30 216.52.146.148/30 using that formula the summ would be 216.52.146.136/28 which is not a valid route. Hoever that formula works here: 216.52.146.48/29 216.52.146.56/29 summ route: 216.52.146.48 /28 I guess my question is, what is the best/effective/convient way to derive summary addresses? Thanks for any input.
