Multiple ISP

KrishnanR — Mon, 15 Jun 2020 10:00:46 GMT

Dear Team,

I have a query. One of the customers wants to load balance their Internet traffic between multiple ISPs ( they have 5 actually). Can we do that ? I know we can do for dual ISP. But will this be feasible ?

@KrishnanR, ECMP would be an option for your requirement but it supports maximum 4 equal cost routes to the same destination. So with this, firewall will actively load balance traffic over multiple equal cost links/paths.

Hope it helps!

In this case, we can't have 5 WAN links right ? The maximum we can do is 4 links with ECMP.

Hello,

Why so many? I'm guessing the ISP's cannot provide the proper bandwidth?

@KrishnanR Yes with ECMP, you can configure maximum 4.
