Senario I have a network lan with 4 vlans going through a 6509 switch. I have a cisco 2921 router that we use as our firewall with Access list. I use access list/nat to route outside IP's to my inside servers.  I'd like to add a second ISP with another block of IP's for failover on the same router. I have DNS Failover setup on the WAN side with a 3 party. Just not sure where to start or if this is even possible.

You want IP SLA.  That configuration will monitor reachability to the end point and, when it's down, will set the next hop to the alternate ISP.

Is that something I have to purchase extra or does that come buy default. Also will I need to set up separate Inbound Access List for the other WAN connection?
