Here is the scenario.
I have a Wimax from my provider which is terminated to my RouterOS via cable on ethernet1.
My capacity is 512kb up and down.
I then have my hotspot on ethernet2 which my users are connecting to for browsing the internet.
The problem is when the link is down then my customers have to suffer.
I want to take a connection from a different provider as well, which again will be cabled and terminated to ethernet3 to act as a backup link.
Since it is going to be rare for both links to go down at the same time, customers will enjoy better uptime.
How can I configure both the links to work togather....
