1134 OSPF Commands
Example
The following example disables OSPF MTU mismatch detection on VLAN
interface 15.
console(config-if-vlan15)#ip ospf mtu-ignore
ip ospf network
Use the ip ospf network command to configure OSPF to treat an interface as
a point-to-point rather than broadcast interface. To return to the default
value, use the no form of this command.
Syntax

broadcast

|

point-to-point

}
no ip ospf network
•

broadcast

•

point-to-point

Default Configuration
Interfaces operate in broadcast mode by default.
Command Mode
Interface Configuration (VLAN) mode.
Usage Guidelines
OSPF treats interfaces as broadcast interfaces by default. L oopback interfaces
have a special loopback network type, which cannot be changed. When there
are only two routers on the network, OSPF can operate more efficiently by
treating the network as a point-to-point network. For point-to-point
networks, OSPF does not elect a designated router or generate a network link
state advertisement (LSA). Both endpoints of the link must be configured to
operate in point-to-point mode.
Example
The following example shows the options for the ip ospf network command.
console(config-if-vlan1)#ip ospf network ?
