It would so be simple. Let us take an example within the same octet
xxxxxxxy (if the least significant bit is 1 for sure this is odd number, on
contrast this number is even number if y is 0)

xxxxxxx1 wildcard 254 ==> you match the least significant bit to be 1, so
you guarantee it is an odd octet.
xxxxxxx0 wildcard 254 ==> you match the least significant bit to be 0, so
you guarantee it is an even octet

Hi All

Does any one can help me in understanding the calculation of even and odd
routes?

Or it would be great if someone has any document.

Thanks
