We have two ISPs, ISP-1 and ISP-2

• ISP-1 is 60mb while ISP-2 is 30mb
• We have ISP-1 terminating physically on a Router, R-1 and ISP-2 terminating physically on another Router R-2.
• R-1 and R-2 are in two separate physical locations. Hi
• How can we utilize the two links at the same time in an Active-Active setup for both Outgoing and Incoming traffic to maximize the bandwidth available without introducing Asymmetric routing into our Internet segment?

@juniorboniface1 hi, below are the options.

1. deploy a link load balancing towards internet and connect two ISPs to the single load balancer or firewall which have capability to link load balancing. so firewall will balance the load through both links with NAT.

2. deploy single router/firewall and connect 2 ISPs. then do PBR. but in this option, traffic need to segregate to two different ISPs in PBR policies.

3. buy a public IP range (AS) and deploy behind 2 ISP routers, so you can manage your public range at your devices and asymetric routing will not be an issue.

Thank you for your response. 
I’ll consider option 3

What has this to do with Collaboration? Are you using the ISP connections for SIP trunks?

[juniorboniface1]

Thank you. 
i’m not using the ISPs as trunks.
