Switch port aggregation at different ISP data rates?

Question

Cisco

There are a couple of switches and a couple of data channels. How the channels are built is not important. The important thing is that one gives 10 Mbps, and the second 4 Mbps. The speed is cut by providers, but the Ethernet-Optics link is actually used.
I know that for LACP to work in Cisco, the ports must operate at the same speed and in the same Duplex mode.
Is link aggregation possible from different providers, with different guaranteed speeds? Would such a system work?

Answer 1

1. LACP without special magic (L2 protocol tunneling) from both providers will not rise. Not everyone has special magic, and those who have it can cost some money. Separately, I note that for the switch, when installing an aggregated interface, the speed at which the link rises may be important, and not what the provider cut with polysers there.
2. Even if it rises, balancing will be done at best based on the mac-ip-port link, at worst - only on mac, and one connection will not get a speed greater than any of the links (random). Even if they were the same, one connection will always rest against one link.
3. Do some sort of active-backup (but even that might not be easy for L2)

Answer 2

Aggregation is the union of L2 lines. And you obviously have L3 lines (the interfaces of different providers are not on the same Ethernet network, and if you put them on the same network, they will be very surprised).
You should look towards Cisco SLA + EEM on L3 interfaces.
