IP Routing Commands

no ip address 

ip-address {subnet-mask | prefix-length} [secondary]

•

ip-address — IP address of the interface.

•

subnet-mask — Subnet mask of the interface

•

prefix-length — Length of the prefix. Must be preceded by a forward slash 

(/). (Range: 1-30 bits)

•

secondary — Indicates the IP address is a secondary address.

This command has no default configuration.

Interface Configuration (VLAN, Loopback) mode

This command also implicitly enables the interface for routing (i.e. as if the 

user had issued the ‘routing’ interface command).

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

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
