I have a small off where we have a 2811 cisco router. We have one connection to an MPLS to the Datacenter where VoIP and other services are ran. We also have another connection off this router to a Sonicwall that is directly connected to a DSL provider. I am wanting to setup where the Sonicwall/DSL is the primary internet connection and if fails goes to the MPLS. The MPLS we have BGP and static routes for.
SonicWall to Router IP: 10.1.1.0/30
Router to MPLS: 172.16.22.0/30
We currently just use the MPLS but with VoIP and Data going accross is killing are bandwidth.
