RHEL 7.3 yum RHEL 6 RPMs

Hello!

I have a 64 bit RHEL 7.3 needing to run a 32 bit application according to the applications customer service. Customer service gave me a list of RPMs needed but they are "el6" which I assume stands for RHEL 6.

This is for a stand alone system so I do a "yum install --downloadonly" and it says that it isn't available for any of the RPMs.

How do I go about getting the information to input into the redhat.repo file to successfully yum RHEL 6 RPMs?

Thanks!
