PCC load balancing not working

RouterOS General

Hi,

I have 2 Wan setup in mikrotik ccr. And PPPoE server setup for clients. Export from my router for dual wan scripting is as following. Still all the traffic is routing through the isp with route distance set to 1. Please tell me where i am wrong in configuration.

Please help me. Dual wan not working properly. most of the traffic is going on TCL wan since its distance is set to 1 in route.

Thanks In advance,

Following is the screenshot of interfaces. see the bandwidth difference.

PCC is never perfectly balanced because is done per tcp/ip connection

is a matter of luck because there is no manner to know how many traffic a tcp/ip connection will transfer

normally this situation is normalized when link is near full utilization.

use simple queues to control bandwidth of the hosts on the two links, that can help to smooth the situation

Hi chechito,

Thanks for the reply. I have setup DMA softlab radius manager with this router. so using simple queue is not possible. Is there any other approach to load balance the bandwidth in effective way?

Thanks in Advance,
Sanket

i have not used that radius implementation because that i dont understand why you cant use simple queuing on the router

i think dis-balance occurs because high bandwidth connections, maybe you have to identify the source or destination of it to think a strategy

try balancing only for source address or by destination address to see if that strategy works better for you
