I would not do that, latency differences will cause issues.  ECMP is simplest.

Subject: Re: [AFMUG] Mikrotik wan bonding using hosted router

I didn't take him to mean bonding DSL with LTE.  I think he's saying bonding 
two identical connections.

I get what you're saying about bonding vs load sharing.

I haven't done it, but I'm certain you could have two identical DSL 
connections, make a tunnel from each one to your data center, then run OSPF 
with equal cost load sharing across those two tunnels.  You still don't have 
more than 25meg on a speed test, but multiple connections in aggregate could 
use 50meg.  That's very easy if both connections perform the same.

Mikrotik's wiki says you can run LAG on top of EoIP.  I have never done this, 
but apparently it's a thing that exists.  The idea frightens me and I don't 
know why.

When you say 25M DSL, are you talking VDSL, or something like ADSL2 which is 
probably already bonded to get that speed?

I’m also thinking that with 2 totally different technologies like DSL and 
cellular, with different latency and packet loss characteristics, you might get 
away with per-destination load sharing but not per-packet.

I usually think of “bonding” to mean something at layer 2, like ADSL supports 
bonding 2 or more copper lines to increase speed.  Or LAG.

But of course the question will be academic in a few months when they can get 
gigabit speeds on 5G.  <insert tongue-in-cheek emoji)

mainly interested as a proof of concept, but say you have a customer who needs 
50m dia and you can only get 25m service (say DSL or LTE) I was interested in 
bonding them to provide redundancy and bonding using a remote mikrotik that can 
provide the tunneling and aggregation

This sounds like a way to cobble an upstream DIA and feed it into a fiber.

Depends on the technology, can you load balance, sure, bonding is a different 
best and needs to be supported by your upstream..

Subject: [AFMUG] Mikrotik wan bonding using hosted router

Has anyone bonded wan interfaces using another mikrotik hosted elsewhere?

I.e. bonding multiple LTE or DSL connections on the wan of a remote mikrotik 
that is tunneled back to another router that has fiber?

Best practices, what works?
