IP Route Command

In this article, I am going to explain the “IP route” command and its parameter, argument, and options in detail. IP route command is used to configure the static route. Static routes are the most secure way of routing. They will also increase overall network performance. These features are extremely helpful in a small network. The syntax of the command is following:

Router(config)# ip route network-address subnet-mask ip-address |interface-type interface-number ip-address ]} [ distance ] [ name name ] [ permanent ] [ tag tag ]

The description of the parameter using ip route command is following:


This is the first parameter. It specifies the destination network address that required to add in the routing table.


The destination network subnet mask to be added to the routing table. We can also use summarized subnet mask for a group of networks to cut the routing table overheads and for speedy processing.


This parameter provides a way to reach the destination network. It is the IP address of the connecting router to use to forward the packet to the remote destination network. This is also called the next hop of the router.


This command also does the same job just like ip-address parameter but in different ways. It specifies the exit interface and tells the router that if it receives a packet for the destination specified by the previous parameter then exits that packet from this interface. Device connected on another end of this interface will take care of the packet.

Note:- One or both of ip-address and exit-interface must be used. 


Administrative distance is the trustworthiness of route. The value of the administrative distance is from 0 to 255. The route with the lowest AD value will be chosen while forwarding the packet. By default static route has two AD values depending on the previous parameter. If static route uses exit-interface, the administrative distance will be 0. If the static route is configured with the next-hop ip address, the administrative distance value will be 0. Usually, this is used to create a floating static route or multiple routes to the same destination. For example, we can create a primary and backup path for the destination network.


we use this parameter to assign a name to the route.


 If we configure the route with parameter permanent, in case a route goes down router will not remove it from the routing table. The parameter permanent will keep this route in the routing table. Its optional parameter we can configure the route without this parameter. This parameter is important for packet security. If you never want packets to take another path.


By using this parameter we can specify a tag number when configuring a static route. The tag can then be matched with a route map. The route map is an access list that allows you to permit, deny, and change parameters of routing advertisements.
