is transparent to the customer network, as if there was a direct physical link between two endpoints
point to point topology
ca be used to interconnect a small number of sites and provide route redundancy at a potentially minimal incremental cost
ring topology
a less expensive option is a point-to-multipoint topology also known as___
hub and spoke topology
spoke sites are connected to each other via hub site and the network communication between two spoke always travel through the hub
hub and spoke topology
any site can communicate directly with any other site that is highly redundant and most desirable WAN topology
mesh topology
modified version of the basic hub and spoke topology
tiered topology
