bgp single router single ISP multihome
Posted on 2013-06-28
My Cisco router has two connections to the ISP and I am using MED for my failover type of connection. My first link is the primary link. My second link is the backup link. It is working currently. Now, I'd like the SAN traffic to take the backup link as its primary link. I was told that route-map may not work as I will have an asymetric routing. In other words, I will have no problem to send the SAN traffic to the backup link. But the return traffic will go through my other link.
I guess once the traffic gets to the ISP, it is out of my control.
Any feedback on how I would accomplish this would be greatly appreciated.
