Which OSPF network command would you use to advertise the 172.16.1.0 network to neighbors?

The command used to advertise the 172.16.1.0 network to OSPF neighbors is structured to define the network address and the wildcard mask properly. In this case, the correct command specifies the network address as 172.16.1.0 and utilizes a wildcard mask of 0.0.255.255, which indicates that any address in the range from 172.16.0.0 to 172.16.255.255, inclusive, will match.

This means that all interfaces within the specified range are included, and any OSPF-enabled interface within that range will be part of the OSPF area specified, which is area 0 in this scenario. Thus, using this wildcard mask allows for the advertisement of all subnets under the 172.16.0.0 range without needing to specify them individually, making OSPF configuration more efficient especially when dealing with numerous subnets.

This approach is particularly vital in larger networks, where summarization can help reduce the size of the routing tables and improve overall OSPF operation efficiency. Hence, the chosen command effectively addresses the need for advertising the specific network.
