You do not define capacities, just load balancing metrics, such as 4:1 or 7:2 etc. L3 is always better right? L2 you can’t do 7:2 so, hence its better right! ☺
The radios should handle the bonding as well, as long as they are the same speed, if not, then they radios will do LACP but guess what, 1:1 only.

What makes L3 preferable to L2 for this? In my particular case, im going to leave the rb1100ahx2 in place and bring the fiber down to HP switches. Mainly because I have the switches and dont want to immediately replace the routers with $1k+ routers until we have settled on the bonding just to get SFP. If L3 is preferred I can just vlan the ports I guess. Another question, is 2+0 normally something that the radios handle the bonding in? This setup is an outlier. It wasnt even listed on SAF as an option for this model until this.

That’s it. OSPF you can acutallly load balance 3:1 or 6:1 etc, but the more connections the better the load balance. But that is the number of connections, not actual load but again, if you have lots of connections then it will balance out. Plus failover is simpler as well (at least in my eyes) Dennis Burgess – Network Solution Engineer – Consultant MikroTik Certified Trainer/Consultant<http://www.linktechs.net/productcart/pc/viewcontent.asp?idpage=5> – MTCNA, MTCRE, MTCWE, MTCTCE, MTCINE For Wireless Hardware/Routers visit www.linktechs.net<http://www.linktechs.net/> Radio Frequency Coverages: www.towercoverage.com<http://www.towercoverage.com/> Office: 314-735-0270<tel:(314)%20735-0270> E-Mail: dmburg...@linktechs.net<mailto:dmburg...@linktechs.net> From: Af [mailto:af-boun...@afmug.com<mailto:af-boun...@afmug.com>] On Behalf Of Mathew Howard Sent: Monday, January 15, 2018 2:01 PM To: af <af@afmug.com<mailto:af@afmug.com>> Subject: Re: [AFMUG] LACP or what for non symetric throughput It looks like Mikrotik supports several different types of bonding, some of which appear to support asymmetrical links. I just started looking into this stuff myself, so I really don't know what I'm talking about... I'm currently just using OSPF to load balance a couple of links, and I'm trying to figure out if there's a better way we should be doing it.

We got dinged by sprint though on the PCN. so we have to drop one sides power on one channel since this path has no other channels. This drops that one chain to 256qam (for reliability) from 1024 so 643-514mbps. This model 2+0 the radios dont communicate so its really just 2 separate links handled externally so I go from (643+643) / (643+643) to (514+643) / (643+643) Is there any way with LACP to account for this single path that will be lower than the other two? There is nothing that fully ties me to LACP. I have the option of HP procurve switches or Mikrotik CCR routers to handle the aggregation. As best I can tell LACP doesnt have any granular throughput definition, just splits traffic across all interfaces (last i read, routeros and the hp OS both allow full aggregate speed instead of single streams being limited to individual port throughput) In my case with 1.2gbps i still have an 800mbpsish overflow issue. so If there is an aggregation thats semi dynamic and granular to actual link capacity, that would tickle my goat any advice from the sages? Id like to keep my switch/routers solution to under 1k per side, much less if possible. I already have HP 1810g-24 that i believe will handle this, so theyre effectively free
