Syntax

no ipv6 ospf hello-interval
<no> - This command sets the default OSPF hello interval for the specified interface.

10.4.2.6 ipv6 ospf mtu-ignore
This command disables OSPF maximum transmission unit (MTU) mismatch detection. OSPF Database
Description packets specify the size of the largest IP packet that can be sent without fragmentation on
the interface. When a router receives a Database Description packet, it examines the MTU advertised by
the neighbor. By default, if the MTU is larger than the router can accept, the Database Description
packet is rejected and the OSPF adjacency is not established.

<no> - This command enables the OSPF MTU mismatch detection.

10.4.2.7 ipv6 ospf network
This command changes 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.
