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

The problem here is most likely due to an incorrect network statement in the OSPF configuration of the new router. The "network" statement specifies which interfaces belong to the OSPF network and should be advertised to other OSPF routers.
In the given configuration, the network statement is "network 10.0.0.0 255.0.0.0 area 0". This statement includes all IP addresses from 10.0.0.0 to 10.255.255.255 because of the subnet mask 255.0.0.0.
If the new router's interfaces are not in this range, they will not be included in the OSPF network and will not be advertised to other OSPF routers. Therefore, the problem is most likely that the network statement is configured improperly.
To solve the problem, the network statement should be updated to include the correct IP addresses and subnet masks for the new router's interfaces. For example, if the new router has an interface with IP address 192.168.1.1 and subnet mask 255.255.255.0, the network statement should be "network 192.168.1.0 0.0.0.255 area 0".
It's also important to note that the process ID, OSPF area, AS, and network wildcard mask should be checked to ensure they are correct, but based on the information given in the question, the most likely culprit for the problem is the network statement.
