By default, which description is true when redistributing routes from other routing protocols into OSPF?（）A. Summarized routes are unacceptableB.

Open Shortes t Path First (OSPF) is a routing protocol developed for Internet Protocol (IP) networks by the Interior Gateway Protocol (IGP) working group of the Internet Engineering Task Force (IETF).Which two statements best describe the OSPF link - state routing pro tocol?（）A. OSPF sends updates every 10 secondsB. OSPF sends triggered updates when a network change occursC.
