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 seconds
B. OSPF sends triggered updates when a network change occurs
C. 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 address
D. OSPF sends summaries of individual link- state entries every 30 minutes to ensure LSDB synchronization
