Which two commands are required for basic OSPF configuration?

To configure OSPF (Open Shortest Path First) on a router for basic operation in a single area, you need at least two commands. These commands are used in the router’s configuration mode. Here they are:

1. `router ospf [process-id]`

– This command is used to enable OSPF on the router. The `[process-id]` is a number you assign to the OSPF process running on the router. It’s locally significant, meaning it doesn’t have to match on other routers, but it’s used to uniquely identify the OSPF process when multiple instances are running.

2. `network [network-address] [wildcard-mask] area [area-id]`

– This command is used to specify which interfaces will participate in OSPF. The `[network-address]` is the IP address you want to include in OSPF, and the `[wildcard-mask]` is the inverse mask of the subnet mask. The `[area-id]` specifies the OSPF area to which these interfaces will belong. In a basic OSPF configuration, all interfaces are often part of area 0.

### Example:

router ospf 1

network 192.168.1.0 0.0.0.255 area 0

– This configures OSPF with process ID 1, and includes all interfaces in the subnet 192.168.1.0/24 in area 0.
