Information
Although the passive interface will neither send nor receive routing updates, the
network on that interface will still be included in OSPF updates sent via 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 interface are marked as passive.
• Any adjacency are 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.
