Multiple acitve ISP's

[bwilliams2]

We would like implement multiple active ISP's. There would be two ISP with each being a different provider.

It appears you can have a redundant setup with multiple ISP, but can you have two active?

@bwilliams2:

You can certainly have two active ISP connections and route traffic to each ISP using Policy Based Forwarding and/or dynamic routing protocols.

What are you hoping to accomplish with your two ISP setup?

Will you be setup on BGP multihoming or will you just have two 0.0.0.0/0 routes?

@bpappas:

The goal is to ensure we are "always" connected. With the shift to the cloud we do not want to limit our connection to one ISP.

@cityofkindsland

I am not sure about the routing at this point. I think I am going to push for a failover connection as apposed to an active-active connection. I am hoping to find an ISP that will allow us to use them on a retainer basis and only pay full price when we reach X amount of data or something along though lines.

Thanks.

failover is a great way to go!  cost savings are great compared to paying for another full service line.

to do this you will go to your virtual router, enter in a 0.0.0.0/0 route out to your failover line with a higher administrative distance than that of your existing link (which should be already set to be 1)

This tells the router use the primary link until it it no longer reachable, after that link goes down use backup link.

Good Luck, let me know if you need anymore help configuing this!
