OSPFv3 Commands 1313
Example
The following example disables OSPF maximum transmission unit (MTU)
mismatch detection.
console(config)#interface vlan 15
console(config-if-vlan15)#ipv6 ospf mtu-ignore
ipv6 ospf network
Use the ipv6 ospf network command in Interface Configuration mode to
change the default OSPF network type for the interface. Use the no form of
the command to return the network setting to the default value.
Syntax
ipv6 ospf network {broadcast | point-to-point}
no ipv6 ospf network
•
broadcast
— The network type is broadcast.
•
point-to-point
— The network type is point-to-point.
Default Configuration
The default state is point-to-point.
Command Mode
Interface Configuration (VLAN, Tunnel, Loopback) mode
User Guidelines
Normally, the network type is determined from the physical IP network type.
By default all Ethernet networks are OSPF-type broadcast. Similarly, tunnel
interfaces default to point-to-point. When an Ethernet port is used as a single
large bandwidth IP network between two routers, the network type can be
point-to-point since there are only two routers. Using point-to-point as the
network type eliminates the overhead of the OSPF designated router
election. It is normally not useful to set a tunnel to OSPF network type
broadcast.
