Question
Site-A and Site- have a site-to-site VPN set up between them. OSPF is configured to dynamically create the routes between the sites. The OSPF configuration in Site- is configured properly, but the route for the tunnel is not being established. The Site- interfaces in the graphic are using a broadcast Link Type. The administrator has determined that the OSPF configuration in Site- is using the wrong Link Type for one of its interfaces. Which Link Type setting will correct the error?

Explanation
We should set p2p on the Ethernet interface to enable automatic discovery of neighbors. Note: OSPF Link type -- Choose Broadcast if you want all neighbors that are accessible through the interface to be discovered automatically by multicasting OSPF hello messages, such as an Ethernet interface. Choose p2p (point-to-point) to automatically discover the neighbor. Choose p2mp (point-to- multipoint) when neighbors must be defined manually. Defining neighbors manually is allowed only for p2mp mode.
