Load balance with MikroTik RB750

[DagegeN]

Hi guys....
Compliments of the season!!!

I have a question for some MikroTik gurus out there, I am in some need for help to setup load balancing with this device and my 3 iBurst modems. I have played around and managed to use only one modem with PPOE but for the life of me i can not get the second or 3rd modem to function.

Can anyone give me a hand, i have also tried the MikroTik forums but the information there are "above my level".

Our guru is out looking after Santa's reindeer. When he returns I'll ask him to post a sample configuration.

Depends on what you trying to achieve. The easiest way is to disable 'add default route' on the PPPOE connection and under IP routes simply add a manual route 0.0.0.0 with 3 gateways (your iburst pppoe connections)

Hey R00i...
Please tell me your guru is back yet

This is quite simple. you have a few options on how to divide client traffic. You have the option of routing a set of clients (full control on which clients gets to use which gateway, by ip address) thru a specific iburst modem (as gateway)
or you can automatically divide clients across the three gateways.
firstly, post your config here. do the following
/ip route export
/ip firewall export
/interface export

i will then check it and correct the config for you, and i can help you over teamviewer to do the config if you like.

Don't know about simple, but definitely doable.

The complication is, unlike say Cisco's inherent CEF routing engine, the Linux kernel underlying Mikrotik does not maintain route hashing persistence (it gets recalculated/altered periodically). So not as simple as adding multiple equal cost default routes out different NAT'd interfaces, since at some point the other host will suddenly see the src address change, breaking communication.

To overcome this, one needs to use Mikrotik's PCC (Per Connection Classifier) functionality to balance & permanently lock IP flows to the outbound interfaces they started on.
