I have the following scenario I am trying configure in BGP. I came up with a
solution using an ACL to match odd/even nets and a route-map to set the med
accordingly. Any thoughts on this? I wanted to check what others might do.

7. AS 36 is to prefer AS 10 for the even networks in 17.17.0.0/22 and the
odd
networks in 32.32.0.0/22. Treat the 17.17.0.0/22 aggregate itself as even.
8. AS 36 is to prefer AS 40 for the even networks in 32.32.0.0/22 and the
odd
networks in 17.17.0.0/22. Treat the 32.32.0.0/22 aggregate itself as even.

[AS10]----[AS36]----[AS40]

Thanks,
Steve
