Chapter 8. Static Routing Concepts

The purpose of this chapter is a last close look into the UNIX routing table and forwarding information base populated with connected interface routes and static routes. Some aspects are fundamental to understand how this view changes when dynamic routing protocols take over control of the routing table. This chapter also discusses certain aspects that UNIX does differently from Cisco IOS Software. Finally, the chapter deals with two special issues: floating static routes and the unique Equal-Cost Multi-Path (ECMP) feature of Linux.
