| IP Interface Commands
IPv4 Interface
– 896 –
Example
In the following example, the device is assigned an address in VLAN 1.
Console(config)#interface vlan 1
Console(config-if)#ip address 192.168.1.5 255.255.255.0
Console(config-if)#
This example assigns an IP address to VLAN 2 using a classless network mask.
Console(config)#interface vlan 2
Console(config-if)#ip address 10.2.2.1/24
Console(config-if)#
Related Commands
ip dhcp restart client (867)
ip default-gateway (896)
ipv6 address (907)
ip default-gateway This command specifies the default gateway for destinations not found in the local
routing tables. Use the no form to remove a default gateway.
Syntax
ip default-gateway gateway
no ip default-gateway
gateway - IP address of the default gateway
Default Setting
No default gateway is established.
Command Mode
Global Configuration
Command Usage
◆ The default gateway can also be defined using the following Global
configuration command: ip route 0.0.0.0 0.0.0.0 gateway-address.
◆ Static routes can also be defined using the ip route command to ensure that
traffic to the designated address or subnet passes through a preferred gateway.
◆ A default gateway can only be successfully set when a network interface that
directly connects to the gateway has been configured on the router.
◆ The same link-local address may be used by different interfaces/nodes in
different zones (RFC 4007). Therefore, when specifying a link-local address for a
default gateway, include zone-id information indicating the VLAN identifier
