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. OSPFv3 Commands 1313
