DSL Failover

I have two DSL connections from the same ISP. They are both PPPOE and there is a static IP Address associated with the PPPOE userid. The ISP only supports PPPOE on these connections.

What I want is to have one enabled and the other disabled in the Mikrotik ver. 2.9. Then, If the Mikrotik detects DSL1 down, it would disable DSL1 and enable DSL2 and sends an email to me.

Then, I would like the reverse to work as well. If DSL2 goes down, it disable’s DSL2, enables DSL1 and sends and email.

By doing it the way I’ve described, I can set the PPOE on both to the same username and pword so it will obtain the same IP.

I’ve looked at the various failover examples in the docs and haven’t been able to come up with a solution that works this way.

Any suggestions?

Thanks…

May I ask you why do you need to obtain the same IP address each time?

I’m guessing its because the inbound traffic is tied to a dns hostname.

If both DSL lines are from the same provider then I would bet that 99% of the time when DSL1 is down that DSL2 would be down as well. . .

Yes on the inbound traffice tied to dns hostname…

As to both DSL lines being from same ISP, they are on seperate copper pair’s going to seperate DSLAMs at the LEC. The idea being that if there are problems with equipment at the LEC, we would still have access.

I know that’s not a great solution, but that’s how they want to go for now.

For traffic tied to hostname, maybe you can try to use changeip or dyndns so that even if your public IP changes you can still be accessible from the internet.

Just a suggestion, get another connection from another provider. In our experience, if the providers network encounters a problem usually it affects the entire network. you would have better chances for redunduncy with a different provider

I thought it was in the manual how to do failover! I did it just by following the MTK manual using ethernet ADSL modems/routers.
