Zorluk: KolayIPv4 Static Routing

A network administrator needs to manually configure a floating static route on a Cisco IOS router to serve as a backup path. Arrange the required command components in the correct sequential order from left to right as typed in the CLI.

  1. 1The command prefix: `ip route`
  2. 2Destination prefix: `192.168.20.0`
  3. 3Subnet mask: `255.255.255.0`
  4. 4Next-hop address or exit interface: `10.1.1.2`
  5. 5Administrative distance: `130`

Cevap

The correct sequence for configuring a floating IPv4 static route in Cisco IOS is: `ip route` keyword, destination network address, subnet mask, next-hop IPv4 address (or exit interface), and administrative distance.
The standard Cisco IOS syntax for configuring an IPv4 static route is `ip route <destination-prefix> <subnet-mask> {ip-address | exit-interface} [distance]`. Placing `ip route` first, followed by the destination network prefix, subnet mask, next-hop IP address, and finally the administrative distance creates a valid floating static route.

Adım Adım Çözüm

1
Identify the global configuration command mode keyword
Start with `ip route`.
Cisco IOS requires the keyword `ip route` to initiate an IPv4 static route entry.
2
Specify target destination network parameters
Provide the destination network IP (`192.168.20.0`) followed by its subnet mask (`255.255.255.0`).
The router must know which destination address block this route applies to.
3
Define forwarding path
Specify the next-hop IP address (`10.1.1.2`) or local exit interface.
The router requires explicit instructions on where to send matching packets.
4
Configure administrative distance for backup behavior
Append an administrative distance value greater than the primary protocol's AD (e.g., `130`).
Setting an AD higher than the primary route (such as OSPF AD 110) ensures the static route remains floating until the primary fails.
