• secondary - Indicates the IP address is a secondary address. Default Configuration This command has no default configuration. Command Mode Interface Configuration (VLAN, Loopback) mode 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. 625
