Some of the best practices for routing are:- Use Dynamic routing protocols like OSPF, EIGRP, or IS-IS instead of Static routing to avoid manual updating the routing table every time something changes. When using Dynamic routing, avoid using RIP due to its limitation on multiple technologies. Use supernet to combine multiple contiguous subnets, making the routing table smaller and manageable. Use a network map to visualize the different network paths available in your network topology. You can either create layer three and layer two diagrams manually or use management software to produce a network map dynamically. Use robust layer three switches or routers with the appropriate CPU and memory to handle large routing tables. Constantly monitor your network for any bottlenecks and adjust your routing methods accordingly to divert traffic towards better available paths. Keep traffic patterns in mind when routing data traffic.
