A network administrator is trying to add a new router into an established OSPF network. The networks attached to the new router do not appear in the routing tables of the other OSPF routers. Given the information in the partial configuration shown below, what configuration error is causing this problem? Router(config)# router ospf 1 Router(config-router)# network 10.0.0.0 255.0.0.0 area 0
正解:C
Explanation/Reference: Explanation: When configuring OSPF, the mask used for the network statement is a wildcard mask similar to an access list. In this specific example, the correct syntax would have been "network 10.0.0.0 0.0.0.255 area 0."
