Bonding or Failover with asymmetric speed interfaces

RouterOS General

Hi,
I want to connect an CCR1036-8G-2S+ (2 SFP+ ports + 8GE) to a CCR1009-8G-1S-1S+ (1 SFP+, 1 SFP, 8GE), the idea is to use the SFP+ ports to connect them at 10Gbps-Full, but I also would like to have some redundancy, so I would like to use the SFP (and if possible to use 1 SFP and 1 GE even better) of CCR1009 as backup so if the 10Gbps goes down, at least there’s a 1Gbps (or 2Gbps) connection.

How can I do that? I have used bonding for symmetrical links, but never for asymmetrical links with a 10:1 ratio.

Thanks!

you don’t (at least, you’re free to test, but the IEEE 802.3ad 2000 specs are limited to same-speed links).

but with that type of CPU power, why not add a higher weighted route for the slower links to achieve the failover as soon as the high speed link goes down?
