The neighbor table shows adjacency state and neighbor identifiers on OSPF interfaces. That is not sufficient here: Passive interfaces suppress OSPF neighbor hello formation while eligible network prefixes remain advertised.
A connected route is installed for an operational interface's configured network prefix. That is not sufficient here: Passive interfaces suppress OSPF neighbor hello formation while eligible network prefixes remain advertised.
The all-zero destination and mask define the IPv4 default route via the next hop. That is not sufficient here: Passive interfaces suppress OSPF neighbor hello formation while eligible network prefixes remain advertised.
