Question
In a redundant hub and spoke "wheel" design, all spokes are connected to the hub, and spokes are connected to other spokes as well. During failure on one spoke link, the traffic from that site can be sent to a neighboring site for it to be forwarded to the hub site. But during peak hours, a link is overloaded and traffic is re-routed to a neighbor, which subsequently becomes overloaded. This overload results in network traffic oscillation as the load varies at each spoke site. This design provides more redundancy but not more resiliency because the routing protocol must process many alternate paths to determine the lowest cost path. Which two design changes help to improve resilience in this case? (Choose two.)
Options
- AIncrease the number of redundant paths considered during the routing convergence calculation.
- BEliminate links between every spoke.
- CIncrease routing protocol convergence timers.
- DIncrease unequal-cost parallel paths.
- EUse two links to each remote site instead of one.
