Administrator Guide

NOTE: Enter the router-id for an OSPFv3 router as an IPv4 IP address.
• Disable OSPF.
CONFIGURATION mode
no ipv6 router ospf process-id
• Reset the OSPFv3 process.
EXEC Privilege mode
clear ipv6 ospf process
Configuring Stub Areas
To configure IPv6 stub areas, use the following command.
• Configure the area as a stub area.
CONF-IPV6-ROUTER-OSPF mode
area area-id stub [no-summary]
• no-summary: use these keywords to prevent transmission in to the area of summary ASBR LSAs.
• Area ID: a number or IP address assigned when creating the area. You can represent the area ID as
a number from 0 to 65536 if you assign a dotted decimal format rather than an IP address.
Configuring Passive-Interface
To 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 mode
passive-interface {type slot/port}
Interface: identifies the specific interface that is passive.
• For a Gigabit Ethernet interface, enter the keyword GigabitEthernet then the slot/port
information (for example, passive-interface gi 2/1).
• For a port channel, enter the keywords port-channel then a number from 1 to 255 (for example,
passive-interface po 100)
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port
information (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 interface
command.
To indicate that hello packets are not transmitted on that interface, when you configure a passive interface,
the show ipv6 ospf interface command adds the words passive interface.
