IPv4 is a connectionless protocol. It operates on a best effort delivery model that does not guarantee delivery or assures proper sequencing or avoidance of duplicate delivery (unlike TCP).
To set the VLAN IPv4 settings:
The OSPF VLAN interface IPv4 configuration screen displays.

                                         Enable Zero Configuration  | 
                                    
                                         Zero configuration can provide a primary or secondary IP addresses for the virtual interface. Zero configuration (or zero config) is a wireless connection utility included with Microsoft Windows XP and later as a service dynamically selecting a network to connect based on a user's preferences and various default settings. Zero config can be used instead of a wireless network utility from the manufacturer of a computer's wireless networking device. This value is set to None by default.  |

                                         Select this option to allow DHCP to provide the IP address for the Virtual Interface. Selecting this option disables the Primary IP address field.  |

                                         Use DHCP to obtain Gateway/DNS Servers  | 
                                    
                                         Select this option to allow DHCP to obtain a default gateway address and DNS resource for one virtual interface. This setting is disabled by default and only available when the Use DHCP to Obtain IP option is selected.  |

                                         Use this parameter to define additional IP addresses to associate with VLAN IDs. The address provided in this field is used if the primary IP address is unreachable.  |
