MikroTik

Hello!
Please help me to adjust load balancing for outgoing traffic.
Have 2 ISP, each of them give us Full View. And have 1 Uplink from both ISP, totally we have 2 uplinks. It is necessary to adjust mikrotik so that the proceeding traffic was distributed between two uplinks in regular intervals, or almost in regular intervals.

ROS v5.0rc8 on x86

Adjust bgp weight so that half of the routes are routed over one peer and other half over another.

But i have 3 nets, and i can use 2 filter on peer. Maybe i don't unerstand where this is doing? Can you be so kind as to show me an example of config?

Hello Sirrin,

I'm also to do BGP Load Balancing with 2ISP and single BGP but is not working.
Other way we need BGP two:
BGP1 peering to ISP1
BGP2 peering to ISP2

I try this way is working.

configure: BGP1 peering to ISP1

I want to do single bgp with multi-home. I do follow (http://wiki.mikrotik.com/wiki/Manual:Si ... ultihoming) on Load sharing setup not failed over
what mistake please help?
