static route between 2 ER8411
I have 2 buildings with each their own oc400, ER8411 and own ISP (static ip pool). I have an wireless connection between both buildings. How would i got about connecting both networks? I take it I need to create a static route? There's several vlans on both sides that need to reach each other. Not all of them but if I manage to setup a connection between all of them, I can maybe narrow it down later. This is all rather new to me ...
I also would like to setup a VPN between both sides as a backup should the wireless setup fail. It might be easier to only use the vpn, but I only have 75Mb upload and the wireless is 750Mb.
I need the connection between both buildings for ip phones and to reach the file server that is on one side.
completely unrelated - and maybe I need to open a seperate topic ...
Was it good practice to install a oc400 on each side or is this overkill and is it better to remove one of them and make 2 sites in one controller?

You just need to setup a site-to-site VPN from one site to the other, allowing LAN subnets between them that you want to be able to allow communications between

i probably made it sound too complicated.
There's 2 seperate networks, one in each building. Imagine I have an ethernet cable between them. I want to connect both sides with the cable to make one big network where clients can reach each other.
I asked chatgpt and it told me to plug in the cable between 2 wan ports, give them a static ip and set them up as trunk. I don't see how to do that.

That's not possible to do.
You have two routers which got two NAT and they don't work like a LAN.
Either you disable the NAT or you create the VPN(Site-to-Site).
Both should resolve what you asked here. If two buildings are interconnected with the same line, VPN would not increase the lantecy.

Can I setup a ipsec between the 2 routers without going over the internet but using a straight ethernet cable instead? I tried, but the tunnel doesn't connect;
I gave Wan/lan10 on both routers a fixed ip (192.168.10.1/24 and 192.168.10.2/24) and as default gateway the 'other side' (192.168.10.2 and 192.168.10.1).
When I setup a tunnel over the internet, using the ISP Wan ports, the tunnel is succesfully created.
I want to connect them with the cable because the bandwidth is much higher than going out and back in over the internet.

Of course. You gotta set the WAN IP in the same subnet and they are physically linked in the same network.
You gave them on the WAN, right?
If you cabling them, why not use a switch as you already have a set of routers and controllers which is the full setup? Adding switches would not hurt the network speed and trouble you creating such stuff like this on both ends which is not improving things. But adding extra layers.
Though it works, not perfect or ideal if you ask someone else to suggest a proper setup.
