You can represent the area IDas a number from 0 to 65536 if you assign a dotted decimal format rather than an IP address.Configuring Passive-InterfaceTo suppress the interface’s participation on an OSPFv3 interface, use the following command.This command stops the router from sending updates on that interface.• Specify whether some or all some of the interfaces are passive.CONF-IPV6-ROUTER-OSPF modepassive-interface {type slot/port}Interface: identifies the specific interface that is passive.– For a Gigabit Ethernet interface, enter the keyword GigabitEthernet then the slot/portinformation (for example, passive-interface gi 2/1).– For a port channel, enter the keywords port-channel then a number from 1 to 255 for TeraScaleand ExaScale (for example, passive-interface po 100)– For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/portinformation (for example, passive-interface ten 2/3).– For a VLAN, enter the keyword vlan then a number from 1 to 4094 (for example, passive-interface vlan 2222).To enable both receiving and sending routing updates, use the no passive-interface interfacecommand.Open Shortest Path First (OSPFv2 and OSPFv3) 573
