IP Routing Commands 617
User Guidelines
This command also implicitly enables the interface for routing (i.e. as if the user had issued the
‘routing’ interface command).
Example
The following example defines the IP address and subnet mask for VLAN 15.
console(config)#interface vlan 15
console(config-if-vlan15)#ip address 192.168.10.10 255.255.255.0
ip mtu
Use the ip mtu command in Interface Configuration mode to set the IP Maximum
Transmission Unit (MTU) on a routing interface. The IP MTU is the size of the largest IP
packet that can be transmitted on the interface without fragmentation. Use the no form of the
command to return the MTU size to the default value.
Software currently does not fragment IP packets. Packets forwarded in hardware ignore the IP
MTU. Packets forwarded in software are dropped if they exceed the IP MTU of the outgoing
interface. Packets originated on the router, such as OSPF packets, may be fragmented by the IP
stack. The IP stack uses its default IP MTU and ignores the value set using the ip mtu
command. 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 mtuignore command).
Syntax
ip mtu integer
• integer — Specifies the distance (preference) of an individual static route. (Range: 68-9198)
Default Configuration
1500 bytes is the default configuration.
Command Mode
Interface Configuration (VLAN) mode
User Guidelines
This command has no user guidelines.
Example
The following example defines 1480 as the MTU for VLAN 15.
