Troubleshooting Metric Redistribution

Hi

I was creating this topology in GNS 3 (version 3.10) . The routers I am using are C-3725 .

When I configure the fa interfaces between R1 and R2 . I get the following message “IP addresses may not be configured on L2 links”.

Could some one guide me where I am going wrong.

 

Thank You
