• secondary: add the keyword secondary if the IP address is the interface’s backup IP address.
To view the conguration, 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.
Example the show config Command
Dell(conf-if-te-0/16)#show conf
!
interface TenGigabitEthernet 0/16
no ip address
shutdown
Dell(conf-if-te-0/16)#
Example of the show ip interface Command

Conguring Static Routes
A static route is an IP address that you manually congure and that the routing protocol does not learn, such as open shortest path rst
(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 congure a static route, use the following command.
• Congure 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 prex-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)
Example of the show ip route static Command
To view the congured routes, use the show ip route static command.
