I took my new favorite simulation and created VRF with NAT. The two areas in the boxes Development and Research have 192.168.48.0 subnets that are identical. I am using NAT so they don’t cross over to the other area. On Development I am using Dynamic NAT with a NAT range of 192.168.96.3 to 31. On Research I did Overload only using 192.168.49.3 for NAT.
