A.When the type-3, type-5 or type-7 LSA changes on the network, the PRC algorithm is used to recalculate the route

B.Compared to PRC algorithm, ISPF algorithm only calculates the changed leaf nodes when the route changes

C.OSPF routers use the FULLSPF algorithm to calculate all nodes in the network when initially calculating routes

D.When the Type 1 and Type 2 LSAs on the network change, the OSPF uses the ISPF algorithm to recalculate the route
