In ArubaOS-CX, to redistribute routes from one protocol into another, you enter the configuration context of the destination routing protocol. For redistributing static routes into OSPF, an administrator would first enter the OSPF router configuration mode (router ospf ). Within this context, the redistribute static command is used to import all static routes into the OSPF process, which then advertises them as Type 5 AS-External LSAs (or Type 7 if in an NSSA) to other OSPF routers.

B. ip ospf static redistribute: This is an invalid command syntax. ip ospf commands are typically applied at the interface level to configure OSPF parameters for that specific interface, not for global redistribution.

C. ospf inject static: The keyword inject is not used for this purpose in the ArubaOS-CX command-line interface. The correct and standard keyword is redistribute.

D. route redistribution static: This is an incorrect command structure. Redistribution is configured from within the routing protocol that is receiving the routes, not as a separate global route command.

"Redistributing routes into OSPF". The guide explicitly lists the command syntax: redistribute {bgp | connected | rip | static | ospf } [route-map ]. The example for static routes confirms the usage.

"Redistributing routes". This section states

"Redistribution is configured within a routing protocol using the redistribute command." It provides a clear example: switch(config-ospf-1)# redistribute static.
