is a process where a router can forward data via a different route for a given destination based on the current conditions of the communication circuits within a system.<ref>Haiyong Xie; [[Lili Qiu]]; Yang Richard Yang; and Yin Zhang.

2004.</ref> The term is most commonly associated with [[data networking]] to describe the capability of a network to 'route around' damage, such as loss of a node or a connection between nodes, as long as other path choices are available.<ref>{{Cite web | url = https://www.pcmag.com/encyclopedia/term/42195/dynamic-routing | title = Definition of | publisher = PC}}</ref> Dynamic routing allows as many routes as possible to remain valid in response to the change.

Systems that do not implement dynamic routing are described as using [[static routing]], where routes through a network are described by fixed paths. A change, such as the loss of a node, or loss of a connection between nodes, is not compensated for. This means that anything that wishes to take an affected path will either have to wait for the failure to be repaired before restarting its journey, or will have to fail to reach its destination and give up the journey.<ref>{{Cite web | url = https://technet.microsoft.com/en-us/library/cc957844.aspx | title = Static and Dynamic Routers | publisher = TechNet}}</ref>
