Young,
Are you allowed to use secondary interfaces in the rip domain? If so use 172.16.X.X/25 for secondary interface. This should work.

I had already tried the method of advertising a default route - in my case,
I had to enter "default-information originate" on R2, which gave R1
connectivity to all networks, including the ones that I couldn't inject into
R1.
Unless someone can prove otherwise, I'm led to believe that either using
static routes or using a default routing are only two methods.
