Conguring 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 {interface-type}
Interface: identies the specic interface that is passive.
– For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport] information.
– For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
– For a port channel interface, enter the keywords port-channel then a number.
– For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
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 congure a passive interface, the show ipv6 ospf [vrf
vrf-name] interface command adds the words passive interface.
Redistributing Routes
You can add routes from other routing instances or protocols to the OSPFv3 process.
With the redistribute command, you can include RIP, static, or directly connected routes in the OSPF process. Route redistribution is
also supported between OSPF Routing process IDs.
To add redistributing routes, use the following command.
• Specify which routes are redistributed into the OSPF process.
CONF-IPV6-ROUTER-OSPF mode
redistribute {bgp | connected | static} [metric metric-value | metric-type type-value] [route-
map map-name] [tag tag-value]
Congure the following required and optional parameters:
– bgp | connected | static: enter one of the keywords to redistribute those routes.
– metric metric-value: The range is from 0 to 4294967295.
– metric-type metric-type: enter 1 for OSPFv3 external route type 1 OR 2 for OSPFv3 external route type 2.
– route-map map-name: enter a name of a congured route map.
– tag tag-value: The range is from 0 to 4294967295.
Conguring a Default Route
To generate a default external route into the OSPFv3 routing domain, congure the following parameters.
To specify the information for the default route, use the following command.
• Specify the information for the default route.
CONF-IPV6-ROUTER-OSPF mode
default-information originate [always [metric metric-value] [metric-type type-value]] [route-
map map-name]
