Three routers; BR1, BR2, and HQ are soon to be connected to a frame relay switch. It is required that the router HQ serves as the main site router which terminates the branch routers BR1 and BR2, so any packets coming from these branch routers is forwarded to router HQ before forwarding to the specific destination. What type of topology should be implemented to satisfy the requirements?
Full Mesh
Partial Mesh
Hub-and-Spoke
Bus
A frame relay hub-and-spoke WAN topology enables a main/central router to act as Hub which terminates the branch routers (Spoke). This topology also allows site to site communication. Packets will traverse through the hub first before being forwarded to the final destination. A full mesh topology allows each and every router to be interconnected to each other which is much expensive to setup. (http://www.kaneezz.com/Ebooks/Cisco/Framerelayguide.pdf)
