MikroTik

Hello. First of all, I'm Brazilian, sorry for my poor English.
I need to configure a network with the following characteristics: 2 internet links (PPPoE) and two networks (LAN1: 192.168.10.0/24 and LAN2: 192.168.0.254/24).
Each network has its own Internet link (LAN1 uses LINK1 and LAN2 uses LINK2). This part I already did using package marking and specific routes for each package mark.

Now, I need to configure it so that when one Internet link down, the other link assumes both networks.
For example:
- LINK1 down -> LAN1 and LAN2 will use LINK2;
- LINK2 down -> LAN1 and LAN2 will use LINK1;
- link returned -> LAN1 resumes using LINK1 and LAN2 resumes using LINK2.

I thank you all.

Hi,

You can see here an example

Thanks for answering.

In the example above, there is only one local network. In my case there are two. This is precisely my greatest difficulty.
I can not make an internet take over the two networks when the other one falls.
I think I'll need to do a script to monitor the two internet links.
I do this configuration on Linux, but on Mikrotik I do not know how to do it.

Can anybody help me?

Thank you.

Hi

Within the existing routing table, as designated by the routing-mark, just add additonal default route going to the other isp, BUT with higher distance.
If first becomes invalid, second will be picked up.

Hi sebastia.

It worked!
I was trying to complicate a simple problem to solve.

Thank you very much.
