WNDR3800 and Multiple Networks

here is a question hopefully someone can answer. I have 3 routers each with it's own internet/DSL in different areas.

right now i use the netgear firmware with static routes pointing to the lan router, windows server 2008r2 using RIP, inteface ip address that is connected in-between all 3 doing the routing. (just to note this same setup does NOT work with the openwrt backfire version

If this can be done using VLANS for the router to router and use RIP routing or something else that would be preferred. What iI would like is to have all the routing to be done in the wndr3700's over the switch ports?

The subnets IP ranges i use is 192.168.1.0 192.168.2.0 192.168.3.0, I can not use the WAN ports are they are used for DSL.

You know what a subnet mask is for right? Specifically one like 255.255.252.0

yes I just typed the incorrect word. I meant IP range.

No I guess you don't... Here is another hint, a computer with an ip address of 192.168.1.100 can talk to computer with an ip address of 192.168.3.100 on your switch (lan side) if they both have a subnet mask of 255.255.252.0

yes i know that but the problem, like was stated in the begining 3 routers each have there own DSL service, DHCP, and DNS and they use those addresses and IP range on each router the 192.168.2.0 255.255.255.0 is one router 192.168.3.0 255.255.255.0 is another router and the third is 192.168.4.0 255.255.255.0 those routers need to talk to each other over the LAN ports. I tell the routers if you look 192.168.3.0 to look at 192.168.2.5. the LAN router will router the traffic off that port only when i use netgears and the same exact setup but when a non-netgear openwrt is used it does not work.

I should have really said 3 seperate networks need to connect over the LAN ports using routing.

No your original post said 192.168.1.0, 192.168.2.0, and 192.168.3.0. It did not mention 192.168.4.0.

ok so yes it looks like what i am doing is called supernetting but it says it needs routing protocols so then how would i do this with the openwrt? I can not find any good infomation to configure this in Gargoyle or openwrt. looks like I need RIP.
