Which three route filtering statements are true?() A. After the router ospf 10 and passive - interface s0/0 commands have been issued , the s0/0 interface will not send any OSPF updates, but will receive routing updates on that interfaceB. When you use the passive - interface command with RIPv2, multicasts are sent out the specified interfaceC.
