2 PPPoE Client WAN PPC to Bridge Interface

Hi, I’m quite new to MikroTik. I just purchased CCR-1009-7G-1C and wanted to create a loadbalance system for 2 of my Internet connection (ISP A: 100/30 Mbps, ISP B: 30/10 Mbps) that are connected to ether1 and ether2. The modem from the two ISP were set to Bridge Mode, so the MikroTik will need to do PPPoE on both connections. In the end, if possible, I would like devices that connected to ether3-7 to be able to use the Internet connection with the combined speed of ISP A and ISP B while also be able to failover to one another.

I’m really sorry if I’m making it too confusing.

Thanks!

ISP A: 100/30 Mbps, ISP B: 30/10 Mbps
Your could set pcc 4/0 or 13/0 in mangle,and set the route 1 or 3 to B, the others to A
Users on ether3-7 shoud be set dhcp users.
Fail over need scheduled script which check the status of pppoe-client on eth1 and eth2 periodly to change the pcc or route.
