Hi.
Well, before I start please look at the attached screenshoot, this is the current config of our network and currently it has only one ADSL connection (marked ADSL 1), now, we want to add another ADSL connection (marked ADSL 2) and do a load balancing between them. Place marked with ADSL 2 is the only place ADSL 2 can be added, no other placement (or plugament) option. Don’t even know if I can do that and if I can please give me some guidelines, links, full howto, offer to do it instead of me, transfer money to my account so nobody has to do it… anything will help…
The image quality of your network diagram is terrible.
I would try and do policy based load balancing, where you let certain subnets (eg. the top half) use ADSL #1 and the remaining subnets use ADSL #2.
If the links were CAT5e/6 cables between the 2 places where the ADSL routers are, then you can try a different load balancing strategy, but using wireless links I would strongly suggest against it.
Please try and get a few opinions about your current setup, and also provide a bit more information like what kind of links you have between the nodes.
Sorry about the quality, image is from The Dude. Lightning like connections are wireless and simple lines are CAT5e so, yes, I am using wireless between ADSL places. Can you please tell me why you do not suggest something other than simply split networks?
Yor only workable option is to route the top half of your network (as seen on your Dude image) thru ADSL1 and the bottom half thru ADSL2.
You will not see any real advantage any other way.
I will add that you could set alternative default routes on the MTs in front of each ADSL line so that they could automatically switch to the other ADSL in case 1 fails (if the failure can be detected).
If you’re determined to try PCC or anything similar, then you should look at creating a tunnel (PPTP or EOIP) between the ADSL-facing Mikrotiks.
Another posibility is routing say HTTP thru ADSL1 and everything else through ADSL2.
That would also have drawbacks though, because you might get complaints that Skype works, but no Web Pages, and then you’d go looking for a DNS failure.
It all depends on bandwidth of your internal network. A better picture indicating spare bandwidth between connections would be needed to determine that. If you have enough internal bandwidth you could route all of your traffic to one (or two) point and distribute it to DSL1 or DSL2.
