Bonding using Balance-rr and 802.3ad

Thu Oct 21, 2021 6:23 pm

Please bear with me as I have little to no networking knowledge. i did some research and found this forum thread:

I have a 1Gbps down & 50Mbps up internet connection that has a max throughput of 1200Mbps. Since the router provided by the ISP only has 1Gbps ports I purchased a RB4011iGS+ to bond two of the interfaces using blance-rr (Router doesn't support 802.3ad) and then bond two further interfaces to my Asus router that supports WAN aggregation using 802.3ad.

This means that I can now fully utilize the 1200Mbps across multple devices concurrently however I've noted that when I upload and download across one or multiple client devices concurrently the upload drops off drasticly. Once the download, using speed test sites for example, is complete the upload speed returns to normal.

All interfaces are showing as 1Gbps Full Duplex.

Can you see any reason for this issue with my config below, or is it some limitation on the technology used?:
/interface bridge
add arp=disabled name=MAIN_Bridge protocol-mode=none
/interface bonding
add link-monitoring=none mode=802.3ad name=LAN_Bond slaves=ether2,ether7 \
    transmit-hash-policy=layer-2-and-3
add link-monitoring=none name=WAN_Bond slaves=ether1,ether6
/interface ethernet switch port
set 0 default-vlan-id=0
set 1 default-vlan-id=0
set 2 default-vlan-id=0
set 3 default-vlan-id=0
set 4 default-vlan-id=0
set 5 default-vlan-id=0
set 6 default-vlan-id=0
set 7 default-vlan-id=0
set 8 default-vlan-id=0
set 9 default-vlan-id=0
set 10 default-vlan-id=0
set 11 default-vlan-id=0
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
/interface bridge port
add bridge=MAIN_Bridge interface=LAN_Bond
add bridge=MAIN_Bridge interface=WAN_Bond
/system clock
set time-zone-name=Europe/London
Thanks,

Carl.
