OSPFv3 Commands

The following example disables OSPF maximum transmission unit (MTU) 

mismatch detection.

console(config)#interface vlan 15

console(config-if-vlan15)#ipv6 ospf mtu-ignore

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.

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.

The default state is point-to-point.

Interface Configuration (VLAN, Tunnel, Loopback) mode

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.
