I have my site connected to two different ISPs, and got 2 different IP blocks. Currently I am using Route policy (PBR) to route the traffic across the links by matching source IP addresses. If any link problem/high latency happens at one of the ISPs I am changing the default gateway of my proxy servers (configured public IPs) to the active ISP.
Can I do some thing on the router to route the packets automatically through the other ISP if one of the ISP goes down.?
or Do i need to get AS no and implement BGP for achevie this redundancy?
Thanks in Advance
