I have a few basic questions about using cisco routers. Hopefully someone can answer these for me.
If i have a two locations with internet access through a local ISP and i have an IPSEC tunnel connecting them what would I use a cisco router for?
I understand that routers segment large networks and reduce network traffic accross a LAN but what advantages do they provide over a WAN?
If I had multiple location all with High speed internet connections and IPsec Tunnels what purpose would the cisco routers perform? I assume that the answer tothis is to route traffic but what protocol would be best to use?
I know that these might seem like basic questions but it will help me get a better understanding of what these routers are fully capable of.
