Traffic Flow & Routing Updates
Once the WAN configuration is established we would review the path that would be used for information to pass from the CO's to the individual schools. But seeing as that is impossible as of now, we came to the conclusion that by using IGRP for the routing protocol, that we could have redundant paths available without causing looping errors. The routers will take into account the traffic flow and use the best route to the source destination. If all goes as well as planned, every router will converge and contain the same data so that no routers will send out bad information to one another. If one of the routers is disabled the district will still be able to offer services and it is not rendered completely inoperable.
With the implementation of IGRP as the routing protocol, the district will have excellent adaptability in the event of a link failure, our routers update every 90 seconds. IGRP has a wide range of metrics to help data travel the network as quick as possible, choosing the best path. By using Split Horizons on interfaces, we reduce the chance of routing loops within the network. Therefore, there are less chance of bringing down the entire district network.
We will also need to implement Simple Network Management Protocol, which is a protocol that allows management to transmit statistical data over the network to a central management console. SNMP requires a management agent component that is contained in the devices that are to be managed. In this case these devices will be bridges, routers, hubs, and switches, which will allow them to be controlled by the management station.
