Reference Guide

● ip-address mask: the IP address must be in dotted decimal format (A.B.C.D). The mask must be in slash prefix-
length format (/24).
● secondary: add the keyword secondary if the IP address is the interface’s backup IP address. You can configure up
to eight secondary IP addresses.
To view the configuration, use the show config command in INTERFACE mode or use the show ip interface command
in EXEC privilege mode, as shown in the second example.
Dell(conf-if)#show conf
!
interface TengigabitEthernet 0/0
ip address 10.11.1.1/24
no shutdown
!
Dell(conf-if)#
Dell(conf-if)#show conf

interface TengigabitEthernet 0/0

Configuring Static Routes
A static route is an IP address that you manually configure and that the routing protocol does not learn, such as open shortest
path first (OSPF). Often, static routes are used as backup routes in case other dynamically learned routes are unreachable.
You can enter as many static IP addresses as necessary.
To configure a static route, use the following command.
● Configure a static IP address.
CONFIGURATION mode
ip route ip-address mask {ip-address | interface [ip-address]} [distance] [permanent]
[tag tag-value]
Use the following required and optional parameters:
○ ip-address: enter an address in dotted decimal format (A.B.C.D).
○ mask: enter a mask in slash prefix-length format (/X).
○ interface: enter an interface type then the slot/port information.
○ distance: the range is from 1 to 255. (optional)
○ permanent: keep the static route in the routing table (if you use the interface option) even if you disable the
interface with the route. (optional)
○ tag tag-value: the range is from 1 to 4294967295. (optional)
To view the configured routes, use the show ip route static command.
