Layer 3 Routing Commands 1738
Command Mode
Interface Configuration (VLAN, Tunnel, Loopback) mode.
User Guidelines
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.
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

no ipv6 ospf network
• broadcast — The network type is broadcast.
