Hi Experts,
We are about to move on to deploy MPLS (with SIP, internet). The MPLS will co-exist with the currently-existing Verizon internet T1 which will be disconnected while the 3 year contract expires next year. I'm very confused about how the two gateways are going to co-exist. Please help me figure if this topology is going to work.
As you can see on the attached file, there will be two gateways -- each from different ISP. Each firewall will be the gateway and handle NAT.
In this case, in order to make the two gateways available to all computers inside the LAN, should I connect Switch-1 and Switch-2? Does it make sense? If not, then how to have pc-A connect to the MPLS?
