Most efficient ACL to match multiple networks - easier way?
Hi Group,
I guess you have all come across a requirement to match multiple networks with a one line ACL.
I understand the theory i.e AND operation to get the network part and X-OR for the wildcard. Now writting out all the networks in binary and doing the operations is time consuming and quite easy to make a mistake when under pressure.
I have tried to work it out using the AND and X-OR functions on the MS calculator and whilst it woks ok for the AND operation for multiple networks, it fails on the X-OR function as it does a comparison of two networks at at time.
Has anybody worked out how to get the calculator to compare multiple numbers using the X-OR function?
BTW it works for AND when using the networks in decimal format…-)
If we crack this, it could potentially save us quite a bit of time.
Regards, Elias PS - The equation for an X-OR gate (for those not familiar with it and may be interested) is: __ Y = (A+B)(AB)
