The "external-out enable" command is available for configuration under the "router ospf process" in case of the IOS-XR operating system. This command basically enables advertisement of intra-area routes on the device as external routes in the OSPF domain.

The "external-out enable" OSPF command should not be turned on without appropriate network planning.
Also it is important to note that the router takes "external-out" command without "enable" keyword under "router ospf". An operator can mistakenly type "ext" instead of “exit” to exit "router ospf config mode" and this can have the “external-out” command configured under "router ospf" unintentionally.
