I have an MPLS network and an Internet connection at 77 remote locations and at my head end locations. I want to create a speedfusion tunnel across my MPLS and Internet connections. When I setup the WAN interface at the head end that is connected to the MPLS router, I am asked to include a DNS server. Can I just include a random address for this or does that connection actually need a DNS server to work? I was hoping that the speedfusion tunnel would just route WAN to WAN across the MPLS network with no need for DNS?
If the WAN doesn’t serve for the purpose of internet surfing, you may put a random address.
