Router to Router VPN with Overlapping internal networks

Hello Experts,

One quick question. How do I configure a Router to Router VPN with overlapping internal networks???

Both of my internal networks have ip address of 192.168.10.0 and 192.168.10.0

Any link or config will be appreciated. I've been looking but no luck.

Thanks,

Randall
