Hello Victor
Notice the following phrase in the lesson:
An attribute flag is 32-bit, meaning you can use this to define 32 separate properties on a link. It’s written in hexadecimal and, by default, all set to zeroes.
You must remember that this 32-bit value is actually a flag. Flag means that it indicates a boolean function, either 1 or 0. So you can actually think of the attribute flag as a series of 32 bit flags. Take a look at this NetworkLessons note on best practices for choosing your attribute flags.
Now in your case, you have overlapping flags because you are using multiple bits for certain link types. So you can’t successfully exclude or include specific traffic unless you follow the best practice in the note, and make the flags unique.
Take a look and try to readjust your flags before attempting the affinity and mask values again.
I hope this has been helpful!
