• 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 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 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information
(for example, passive-interface ten 2/4).
– 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.
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]
Configure 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 configured route map.
–tag tag-value: The range is from 0 to 4294967295.
Configuring a Default Route
To generate a default external route into the OSPFv3 routing domain, configure the following parameters.
To specify the information for the default route, use the following command.
• Specify the information for the default route.
