This multimodal network with Cisco devices was made in the simulator Packet Tracer [Networking Academy] and can be downloaded here [MultiModalNetwork].
In the network shown above, there are 5 main parts:
1 – One EtherChannel network on the left that interconnects both switches, merging 8 bridge ports into one and creating a single 8 Gbps link between them. This solves the bottleneck of having only one 1 Gbps link. Read more about EtherChannel [Read It].
2 – RIP was applied to the top section of the network to automatically adjust routes between the server and the larger network. This technology is simple and works well, but has limitations on larger networks. Read more about RIPv2 [Read It].
3 and 4 – OSPF multilayer routing is used in the center and right sections of the diagram. On larger networks, it is wise to break them into segments so that OSPF can reduce the size of routing tables in each router and lower the network traffic generated by OSPF.

5 – At the bottom of the diagram, EIGRP was used to connect the server to the rest of the network. It is a powerful routing protocol worth considering when all infrastructure is Cisco, as this protocol is proprietary to Cisco. Read more about EIGRP [Read It].
