How is router redundancy completed between 2 different subnets? Or can it?
Requirements:
Ext-PC1 and Ext-PC2 need to be able to access Int-Server1 and Int-Server2 regardless of router outages.
My thinking is to put Ext-RTRs and Int-RTRs on the same subnet and run VRRP between them.
Thanks for any help.

I suppose that this 2 PCs are in different VLANs right? I would go with this solution:
- connection between Ext-RTR1 and Ext-RTR2 and switch stack - trunk;
- subinterface which corresponds to 2 VLANs subnets on both routers (with coresponding addressing);
- HSRP or VRRP with 2 groups configuration on routers - one router primary for one VLAN, second one primary for other VLAN.

Your diagram alrealy shows the two Int-RTRs on the same subnet with HSRP/VRRP. What you want to do is have both Ext-RTRs on both PC subnets, also running HSRP/VRRP. Additionally you might want both your Ext-RTRs and Int-RTRs to attach to both edge switches.
