Hey there! I've been working away at this for a while now, still no luck...
I looked at a bunch of documentation and other posts on the forum, still not sure what I'm missing.
I'm simulating networks using GNS3, I use OpenWRT for my routers and host all instances on a VM. There are currently 2 LANs, 192.168.1.0 and 172.60.2.0, each using an OpenWRT router. I refer to 192.168.1.0 as "Red" and 172.60.2.0 as "Blue."
As for the configs, this is what I have at the moment:
/etc/config/network (Red)
config interface
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1/8'

# *** IPv6 stuff that I don't think matters rn since I'm working with IPv4 ***
As for the topography, each LAN has a DHCP server, the router, and some devices (hosts 100 and 101) connected to a switch. The red and blue routers are physically connected and are supposed to communicate over the backbone 1.1.1.0.
In its current state, hosts 100 and 101 on either LAN can ping each other and their respective routers. The routers can ping each other. However, 100 red cannot ping 100 blue, nor can 100 red ping the blue router, and I don't know how to fix this.
Any and all help is appreciated!
