COMMAND USAGE
You can configure an OSPF interface as passive to prevent OSPF routing
traffic from exiting or entering that interface. No OSPF adjacency can be
formed if one of the interfaces involved is set to passive mode. The
specified interface will appear as a stub in the OSPF domain. Also, if you
configure an OSPF interface as passive where an adjacency already exists,
the adjacency will drop almost immediately.
EXAMPLE
Console(config-router)#passive-interface vlan 1
Console(config-router)#
show ip ospf This command shows basic information about the routing configuration.
SYNTAX
show ip ospf [process-id]
process-id - The ID of the router process for which information will
be displayed. (Range: 1-65535)
