Routers R1 and R2 are OSPF neighbors using their Fa0/0 interfaces, respectively, using default settings for all timers. An engineer ad ds the ip ospf hello - interval 6 command to R1‘s Fa0/0 configuration.Which of the following is true regarding the results from this change?（）A. The show ip ospf neighbor command on R1 lists the revised Hello timerB. The show ip ospf interfac e brief command on R1 lists the revised Hello timerC.

OSPF is a link-state routing protocol。It is designed to be run internal to a single （）system。Each OSPF router maintains an identical （）describing the autonomous system’s topology。From this database，a routing table is calculated by constructing a shortest-path （）。OSPF recalculates routes quickly in the face of topological changes，utilizing a minimum of routing （74） traffic。OSPF provides support for equal-cost multipath。An area routing capability is provided，enabling an additional level of routing protection and a reduction in routing protocol （）。A.protocol
B.network
C.broadcast
D.multipath
