The Art of Networking

Like much in life, there are levels of routing and switching that can be accomplished with minimal effort to establish simple connectivity, and then there are more advanced levels, achieved through careful tuning and consideration that result in a work of art. If designing optimized networks is something you aspire to, then one of the most important things you can do is put some thought into how you want traffic to flow through the network. To do that, consider some of these questions, which you can use as part of a checklist when you design a network:

Do layer 2 and layer 3 match? Be careful to configure the network so that Spanning-Tree and your routing protocol compliment each other instead of conflict.

Is routing synchronous? That is, if you have multiple paths, does traffic flow in and out the same path? or does it go out one and come back in on the other? Sometimes it doesn't matter, other times it's critical, but mostly, it's part of load-balancing which in turn is an important part of tuning your network. The Art of Networking
