If you use secondary addresses, how do you deal with the split horizon

I've tried this and yes it works.
Care have to be taken though, I was testing on different IOS version and
guess what...they all got
different behaviour. Some works some don't. So, it all depends on which IOS
you are using.

Would a secondary addresses on R2 and R1 in the range of 172.16.100.9/29
work? Please let me know
if it does.

The solution stated in the document requires static routes, which I'm not
allowed to do. Is there any other way to accomplish the object without
using static routes?
