While the passive-interface default command prevents all interfaces from establishing an OSPF neighborship, the no
passive-interface vlan 20 command enables the interface for VLAN 20, the OSPF peering VLAN, to establish OSPF adjacencies.
The following output displays that Dell-1 forms neighborship with Dell-2 and R1.
