I have two different ISP's connected to seperate routers, and multiple IP blocks with your typical BGP configuration for failover.
My issue is that one of my /24 networks sends and recieves more traffic than some of my other networks, and one of my Internet connections is less used than my primary connection.
I have configured by prepending the as-path that inbound traffic to that block comes in my less used ISP and in a failover fails to my other ISP.
What I cannot seem to get to work is outbound traffic sourced from that network to the Internet. I do have it working with Policy-Based Routing, but if one of my ISP's fails then PBR just keeps looping between my routers as I have my policy looking on my ethernet interfaces.
Wanted to see if anyone had any ideas on how best to accomplish this.
I had looked at OER, but I am not sure I am ready to put that into production yet unless someone convinces me otherwise.
Thanks in advance.
