The PfR-important items are highlighted below. You need to set an accurate figure for the expected bandwidth on the link and set load statistics interval to the lowest setting (30 sec). Also note that both interfaces are designated as 'outside' for NAT.

PfR Master Router ConfigConfiguring the Master is easy as well. In fact, just defining the key-chain and the internal+external interfaces is enough to enable basic load-balancing + fail-over. PfR will aggregrate routes on IP address prefixes and balance across those routes across the 2 ISP links.

With a UNIX variant this would be best done with a bond, then it would just be a matter of selection which bondmode you wanted. What OS are you using?TerryFrom: SIVAKUMAR.AS via networkadmin-l mailto:[email protected]: Monday, September 20, 2010 12:59 PMTo: Mahan, TerrySubject: networkadmin-l Load Balancing between two isp is same router with Static routePosted by SIVAKUMAR.ASon Sep 20 at 1:05 PMDear All,How to configure load Balancing when two ISP link ISP1 512 Kbps and ISP2512Kbps are terminated in same Router with static routeIf one goes down link should from other ISP.When both are up lan should get1 Mbps.Please suggest. The key is how are you adding the interfaces for the two ISPs, can you list the commands? If they're similar to adding Ethernet interfaces than you should be in luck. Then check the man page for that command to make sure bond is supported with that for your Linux distribution and if so which bond modes are available, some are more active/passive, others are more active/active as you seem to desire.

You'll then want to check the router docs to make sure they can handle the bond mode you prefer.TerryFrom: SIVAKUMAR.AS via networkadmin-l mailto:[email protected]: Monday, September 20, 2010 9:31 PMTo: Mahan, TerrySubject: Re: networkadmin-l Load Balancing between two isp is same router with Static routePosted by SIVAKUMAR.ASon Sep 20 at 9:32 PM Mark as helpfulDear Terry,We are using Linux and Techroute router.

I think there is some confusion with the difference between load balancing and bonding.From my research I have only found 1 device (mushroom networks) that can bond 2 connections from different ISPs.
Mar 4, 2018 - Cisco Performance Routing - Dual ISP's, Single Router. It would not provide load-balancing of those links though. PfR provides both.
In most cases, bonding needs to be done and the ISP and the Router.Bonding is a method of treating 2 connections as an aggregate connection.
