broadcasts are dropped.
ip netdirbcast
no ip netdirbcast
Parameters
None
Default
The default is Disable.
Command Mode
Interface Config
7-28 ip mtu
Set the IP Maximum Transmission Unit (MTU) on a routing interface or range of interfaces. lP MTU is the
size of the largest IP packet that can be transmitted on the interface without fragmentation. Forwarded
packets are dropped when IP MTU exceeds outgoing interface.
Packets originated on the router, such as OSPF packets, may be fragmented by the IP stack.
OSPF advertises the IP MTU in the Database Description packets it sends to its neighbors during
database exchange. If two OSPF neighbors advertise different IP MTUs, they will not form an adjacency
(unless OSPF has been instructed to ignore differences in IP MTU with the ip ospf mtu-ignore
command).
No command resets the ip mtu to the default value.
ip mtu 68-9198
no ip mtu
Parameters
None
Default
The default is 1500 bytes.
