'''Static routing''' is a form of [[routing]] that occurs when a router uses a manually-configured routing entry, rather than information from a dynamic routing traffic.<ref>[http://www.redbooks.ibm.com/redbooks/pdfs/gg243376.pdf TCP/IP Tutorial and Technical Overview (IBM RedBooks Series)]</ref> In many cases, static routes are manually configured by a [[network administrator]] by adding in entries into a [[routing table]], though this may not always be the case.<ref name=SLA>http://www.cisco.com/c/en/us/td/docs/ios/dial/configuration/guide/12_2sr/dia_12_2sr_book/dia_rel_stc_rtg_bckup.html</ref> Unlike [[dynamic routing]], static routes are fixed and do not change if the network is changed or reconfigured. Static routing and [[dynamic routing]] are not mutually exclusive. Both dynamic routing and static routing are usually used on a router to maximise routing efficiency and to provide backups in the event that dynamic routing information fails to be exchanged. Static routing can also be used in [[stub network]]s, or to provide a [[default route|gateway of last resort]].
