Summing Up
The administrative controls described in this chapter are useful tools for the network engineer to have in her back pocket. To ensure that the network engineer is not being constantly called on to use these tools to “patch” the network, it is important that the overall routing architecture be simple and elegant. Toward this end, it may be prudent for the network engineer to pay attention to the following:
Hierarchy of design, reflecting a hierarchy of IP addresses
Route summarization, reducing the size of the routing table
Using only a small number of routing protocols in the network, as it is difficult to be familiar with the vagaries of several different routing protocols or to handle multiple route redistributions
Further, since all IOS versions exhibit bugs, limit the number of IOS versions used in the network.
