Redundancy refers to the duplication of devices, services, or connections so that, in the event of a failure, the redundant devices, services, or connections can perform the work of those that failed.
We have added three additional routers and four additional paths to our intial LAN design. More routes means more routing updates will be needed. Time to convergence will slightly increase, but this should not have a serious negative impact on communications across the District.
In the event of a core router failure, we have in storage a spare router with the exact same configuration. All we will have to do is take it out and plug it in, thereby minimizing disruption to the network.
