Is this possible


Im trying to make this work. Is this possible in openwrt?
Referencing to the picture, I have 2 identical router, one is for receiving two internet connection from 2 different wwan, and another one for AP.

The two router is connected using two ethernet cable, which one of them only for download and another ethernet cable for download. Im trying this because i want to increase my bandwidth. For router A I split this two ethernet using 2 LAN port. For router B, I use WAN port and one LAN port (repurposed to WAN 2).

Both router have MWAN3 installed for loadbalancing. How i can make this work with MWAN3 and what should i use or edit to make this work.

Look into luci-proto-bonding for your link aggregation needs.

Since gigabit (and most 100 Mb) Ethernet is always full duplex, there is no need for separate cables in each direction. In other words, the transmission speed of a cable is always at the full rate, it does not have to wait on traffic in the other direction on the same cable.

If one wants speed from 2nd cable LAG does that.
