Hi, Emil
I think you should use
Access-list 10 permit 212.18.1.0 0.0.254.255 for odd route.
The only difference between odd and even routes is the least
significant bit of the 3rd octet.
So you need to keep this bit from changing but allow all other bits.
You can try to convert them into binary, you will see they are not that subtle.
HTH.
Regards
Lin
