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. When a link state is changed, the router that detected the change creates a link - state advertisement (LSA) and propagates it to all OSPF devices using the 224.0.0.6 multicast addressD. OSPF sends summaries of individual link- state entries every 30 minutes to ensure LSDB synchronization
