Implementing Static Routes on Cisco IOS XR
Software
Static routes are user-defined routes that cause packets moving between a source and a destination to
take a specified path. Static routes can be important if the Cisco IOS XR software cannot build a route
to a particular destination. They are useful for specifying a gateway of last resort to which all unroutable
packets are sent.
This module describes the tasks you need to implement static routes on your Cisco IOS XR network.
Note For more information about static routes on the Cisco IOS XR software and complete descriptions of the
static routes commands listed in this module, see the “Related Documents” section of this module. To
locate documentation for other commands that might appear while executing a configuration task, search
online in the Cisco IOS XR software master command index.
