Something I don't understand though is why can't I route the traffic through a core router through a vpn.
Office A is the data center with the 3030 and a Large core router. Office B and C are connected to Office A but do no know of each other.
Then route all the traffic for our class B network through the core.
I've tried to do this but I can't get the IP route statement to travel the Vpn tunnel. I'm still learning about all of this and any help would be great.
