Day 7 - WAN Flashcards
What are the 4 basic WAN topology options?
Point-to-Point
Hub-and-Spoke
Full mesh
Dual homed
Solve for the definition of WAN topology:
Typically uses a dedicated leased line connection, such as a T1 or E1
Point-to-Point
Solve for the definition of WAN topology:
Offers a single homed, point-to-multipoint topology in which a single interface on the hub router can be shared with multiple spoke routers through the use of virtual routers
Hub-and-Spoke
Solve for the definition of WAN topology:
Gives each router a connection to every other router. Requires a large number of virtual interfaces
Full mesh
Solve for the definition of WAN topology:
Provides redundancy for a single-homed hub-and-spoke topology by providing a second hub to connect to spoke routers
