5508-X “Advanced Routing” scenario (Connecting 2 seperate established Subnets)

[fbeye]

Hello... I posted an extremely similar discussion but I believe I may have explained it and myself incorrectly. Thank you regardless to those who assisted.

Here is my situation; I have 2 already established and functioning networks.

Router 1, 10.0.1.1, is giving out 10.0.1.101-10.0.1.120.

Router 2, 10.0.2.1, is giving out 10.0.2.101-10.0.2.120

Both of those Routers are residential WiFi Routers and they themselves have static IPS through Cisco 5508-X and both have Internet access.

 What I want to do is create a link between both LANS of each router. 

Simply put, I want anyone on 10.0.1.x to access (specifically) my NAS on 10.0.2.115.

I know that to connect 2 Networks I need a L3 Device... 

Would I be able to utilize Gigabitethernet 6 and 7 to link both routers? They need no internet access GE 6 and 7 only access to connect to the other LAN.

I am to believe each Interface on my 5508 is L3 so I thought this would be a solution.

where I am lost at is how to deploy this. Such as would the GE 6&7 be their own Subnets or would they use an up from each router they connect to like 10.0.1.114 and 10.0.2.114 to extend off the WiFi routers. Would i need NAT for both interfaces to communicate? As I said I just want straight across the board access. I was also thinking of making both 6/7 security level 90 opposed to 100 as my other interfaces.

any guidence  would be wonderful

Thank you both. With both of your direction I have finally come to resolve the situation and it works as I had hoped.

My 10.0.1.x Subnet on Router 1 and now access the NAS on my 10.0.2.x Subnet on Router 1 on the LAN side.

Thank you so much. Thank you.

I did want to mention that in the end what I did was use my 5508-X and made Interface 7 10.0.1.115 and Interface 8 10.0.2.115. I then created the IP Routes as mentioned on both the VPN and Open WiFi Routers and that was it. No NAT or ACL.

10.0.2.0 255.255.255.0 10.0.1.115 and then 10.0.1.0 255.255.255.0 10.0.2.115.

Thanks for the update. This confirms my earlier suggestion that you should be able to accomplish your requirement using the ASA. I am glad to know that you have it working and did not require use of an additional switch.
