IP Interface Commands
41-4
41
uses a secondary address, all other routers in that segment must also use a
secondary address from the same network or subnet address space.
• If
bootp
or
dhcp
options are selected, the system will immediately start
broadcasting service requests. IP is enabled but will not function until a
BOOTP or DHCP reply has been received. Requests will be broadcast
periodically by this device in an effort to learn its IP address. (BOOTP and
DHCP values can include the IP address, default gateway, and subnet mask).
• BOOTP or DHCP requests can be broadcast for all VLANs configured to
obtain address assignments through BOOTP or DHCP by entering the
ip
dhcp restart client
command, or by rebooting the router.
Note:
Each VLAN group can be assigned its own IP interface address. Therefore, if
routing is enabled, you can manage the router via any of these IP addresses.
Example
In the following example, the device is assigned an address in VLAN 1.

ip default-gateway
This command specifies the IPv4 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 static route is established.
Command Mode
Global Configuration
Command Usage
• The gateway specified in this command is only valid if routing is disabled with
the
no ip routing
command (page 42-1). If IP routing is disabled, you must
define a gateway if the target device is located in a different subnet.
• If routing is enabled, you can still define a static route using the
ip route
command (page 42-2) to ensure that traffic to the designated address or
subnet passes through a preferred gateway.
Console(config)#interface vlan 1
Console(config-if)#ip address 192.168.1.5 255.255.255.0
Console(config-if)#
