I make a 10 wan load balance (dsl) with PCC, but i have a big problem, in my country sometimes we have a intermitent down of a various adls at same time, sometimes i have 4 or 5 wand down at same time, this is a big problem because the RouterOS send all the traffic of this 5 down wan for the default gateway saturating this link, i make a script that first count the number of active routes and then re-create the mangle rules changing the PCC parameter and inserting the new rules. maybe is more easy to resolve this issue (i wait opinions) but this is the way i think by now.
i dont know much about scripting, maybe there is best and easy way to do this, i’ll wait advices.

Hi max, this is working in my router i dont know whats the problem..
hola, max nos conocimos en el mum de argentina, el script que esta alli lo copie y pegue de la configuracion actual, aca te pegare el mismo pero con algunas modificaciones que he hecho sobre la marcha, pero como te digo esta trabajando en una rb493 con v4.5

Thanks Janisk for edit the code part and show me that it’s possible, jejeje
Load balancing and failover does not work properly.
Until 2019, load balancing and failover not worked properly.
High time to do something about it.
This would be a great asset for the Mikrotik routers
No Chupaka, he has been unable to get mangling and PCC working in another thread so he bitches about it like spam everywhere else.
However, if you want to help out, I would ask that you join us at this thread as I have been unable to solve what should be straightforward… http://forum.mikrotik.com/t/load-balancing-dont-work/128208/1
What I find interesting on this thread is that the configuration is designed to deal with not all the WANs being available and thus I see no need for a script??
In the mangled routes, we check gateway = ping. Thus if one is not available the load is distributed amongst the remaining mangled routes and so on?
What am I missing in the logic??
Caveat: I cannot script or MT config myself out of a paper bag.
I am talking about the tutorials that were made and in which year. Steve Discher’s tutorial is not working.
Something must have changed in the Mikrotik routers.
In RouterOS 6.37 the load balancing and failover worked perfectly.
There is also a failover tutorial made in 2019 (PDF file) and this does not work either. This is what I mean.
If I send a supout.rif to Mikrotik they are very vague and give no concrete solution.
What do you mean with my account hacked.
My Mikrotik account or forum account?
is a joke, the antenna is about 2 m radius
