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. 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.
