  • Static Route

    A static route is one that a network administrator creates manually.

    The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols.

    Static routes have advantages and disadvantages when compared to dynamic routes.

    Advantages of Static Routes:

    • Easy to configure
    • No routing protocol overhead

    Disadvantages of Static Routes:

    • Network changes require manual reconfiguration
    • Network outages cannot be automatically routed around

    Creating a Static Route under Unix

    Under Unix, static routes can be created using the `route` command.

    The example shows the creation of a static route for a single host:

    # route add
    add net gateway

    The user can see the static route that was created with the `netstat -nr` command:

    # netstat -nr
    Routing tables
    Destination Gateway Flags Refs Use Netif Expire
    ... UGS 0 0 fxp0

    Creating a Static Route under Cisco IOS

    To add a static route on a Cisco router, use the `ip route` command.

    The syntax to utilize is: ip route &ltdestination> <netmask> <next hop>.

    The example shows the creation of a static route for a single host:

    FAQ-Cisco# conf t
    FAQ-Cisco (config)# ip route
