Is it possible to use Multi WAN with CAKE Autorate?

Installing and Using OpenWrt Network and Wireless Configuration
1

I have two LTE routers/modems from two different ISPs. Currently, I only have on of them (working in bridge mode) attached to my EdgerouterX running OpenWrt, which is my main network router, and the other one is just laying unused.

I would like to use both LTE modems as WANs, and mwan3 package seems to allow that pretty easily. But I also need to use CAKE SQM with cake-autorate, because without that LTE internet in my location is unusable.

So the setup of my OpenWrt router I am thinking about is something like:

LTE-1 --> mwan3 --> CAKE (managed by cake-autorate) --> VLANs 
LTE-2 ----^

But would something like that even work?

I couldn't find any information about such setup, because cake-autorate is fairly new technology and Multi WAN is not very common.

The current main cake-autorate branch (called master) should support that out of the box, you will need to create one config file per link and read the supplied default config file carefully to learn how to configure things for mwan3. Also be aware that this feature has not seen all that much testing, so we have no idea how generically useful it is right now.

That is good to know cake-autorate supports that, thanks. I'm more than happy to be a tester of this feature.

Does this mean I need to run two CAKE instances for each wan interface?

Yes. SQM allows multiple concurrent shaper setups (as long as they are instantiated on different interfaces) for an 'easy' way to set something like that up.
