Hi,
New to the board. I have two WAN circuits going to two separate ISPs. I would like to run ECMP with weighted round robin over ISP1 & ISP2. However, I want to verify this can be achieved successfully in my environment. I have 15-20 VPN connections to various agencies which all must go out the correct circuit (ISP1) and IP address. I have hard coded these in as destination NAT rules and they work fine but currently I am only using ISP1 and ISP2 is strictly a backup. I have read a few articles stating this is possible but that I would need multiple VRs. I currently only have one VR in place. Is there a good document somewhere with detailed configuration steps or could someone tell me if this configuration would work in my environment?
Thank you very much in advance!

Hi @justinmoose ,
As far as I know you can ECMP using just one VR.
Please check out the following KB on how to implement ECMP:

In this light board presentation, you will learn the benefits of deploying ECMP, and review a basic topology of how to configure ECMP in your network:
