[多项选择]Which two are characteristics of link-state routing protocols?() (Choose two.)
A. Routers choose a best path for a destination based on the SPF algorithm.
B. All routers in a given area or level build a consistent database describing the network's topology.
C. Routers choose the best path for a destination based on the interface on which they received the link stateadvertisement with the lowest cost.
