Difficulty: EasyIPv4 Static Routing

A network administrator needs to manually configure a backup floating static route on a Cisco IOS router. Arrange the following syntax elements in the correct sequential order from left to right to construct a valid Cisco IOS floating static route command.

  1. 1ip route
  2. 2172.16.1.0
  3. 3255.255.255.0
  4. 410.1.1.2
  5. 5130

Answer

The correct sequence to construct the command is: ip route 172.16.1.0 255.255.255.0 10.1.1.2 130.
The correct order follows the standard Cisco IOS static route syntax: 'ip route <destination-prefix> <subnet-mask> {ip-address | exit-interface} [distance]'. The command starts with 'ip route', followed by the target destination network (172.16.1.0), the subnet mask (255.255.255.0), the next-hop address (10.1.1.2), and finally the optional Administrative Distance value (130).

Step-by-Step Solution

1
Begin with the global configuration command keyword.
Specifies 'ip route' at the beginning of the command string.
Cisco IOS requires the 'ip route' command keyword to define a static routing entry.
2
Append the destination network address followed by its subnet mask.
Adds '172.16.1.0 255.255.255.0'.
The router needs the target IP subnet prefix and corresponding subnet mask to evaluate match length in the routing table.
3
Specify the next-hop IP address or local exit interface.
Adds '10.1.1.2'.
Defines the forwarding destination or gateway to reach the target network.
4
Append the optional Administrative Distance value at the end.
Adds '130'.
Assigning an Administrative Distance higher than the primary route (e.g., OSPF AD 110) creates a floating static route that remains inactive until the primary route drops.
