Version Description
7.8.1.0 Added support for Multi-Process OSPF.
7.6.1.0 Introduced on the S-Series.
7.5.1.0 Introduced on the C-Series.
7.4.1.0 Modified to include the keyword default.
6.1.1.1 Introduced on the E-Series.
Usage Information
Although the passive interface does not send or receive routing updates, the network on that interface is still
included in OSPF updates sent using other interfaces.
The default keyword sets all interfaces as passive. You can then configure individual interfaces, where
adjacencies are desired, using the no passive-interface interface command. The no form of this
command is inserted into the configuration for individual interfaces when the no passive-interface
interface command is issued while passive-interface default is configured.
This command behavior has changed as follows:
passive-interface interface
•
The previous no passive-interface interface is removed from the running configuration.
• The ABR status for the router is updated.
• Save passive-interface interface into the running configuration.
passive-interface default
• All present and future OSPF interfaces are marked as passive.
• Any adjacency is explicitly terminated from all OSPF interfaces.
• All previous passive-interface interface commands are removed from the running configuration.
• All previous no passive-interface interface commands are removed from the running
configuration.
no passive-interface interface
• Remove the interface from the passive list.
• The ABR status for the router is updated.
• If passive-interface default is specified, then save no passive-interface interface into
the running configuration.
No passive-interface default
• Clear everything and revert to the default behavior.
• All previously marked passive interfaces are removed.
• May update ABR status.
redistribute
Redistribute information from another routing protocol throughout the OSPF process.
C9000 Series
Syntax
redistribute {connected | rip | static} [metric metric-value | metric-type
type-value] [route-map map-name] [tag tag-value]
To disable redistribution, use the no redistribute {connected | isis | rip | static}
command.
Parameters
connected Enter the keyword connected to specify that information from active routes on
interfaces is redistributed.
rip Enter the keyword rip to specify that RIP routing information is redistributed.
static Enter the keyword static to specify that information from static routes is redistributed.
