What Is A Characteristic Of a Floating Static Route?

Introduction

The Cisco Certified Network Associate (CCNA) 200-301 certification is a globally recognized credential that validates a professional's ability to install, configure, and troubleshoot network devices. One of the essential topics covered in the CCNA exam is static and dynamic routing, including a specialized type known as a floating static route.

In this comprehensive guide, we will explore:

  • What is a floating static route?
  • Characteristics of a floating static route
  • How floating static routes work in Cisco devices
  • Configuration examples
  • Why understanding floating static routes is crucial for the CCNA 200-301 exam
  • How Study4Pass can help you prepare effectively for the CCNA certification

By the end of this article, you will have a solid understanding of floating static routes and their role in network redundancy, ensuring you are well-prepared for the CCNA 200-301 exam.

What Is a Floating Static Route?

floating static route is a manually configured backup route in a Cisco router that becomes active only when the primary route (usually a dynamic route) fails. Unlike regular static routes, which have a default administrative distance (AD) of 1, a floating static route is assigned a higher AD to ensure it remains inactive unless the primary route is unavailable.

Key Characteristics of a Floating Static Route

  1. Higher Administrative Distance (AD):
  • The primary characteristic of a floating static route is its higher AD compared to the primary route.
  • For example, if the primary route is learned via OSPF (AD = 110), the floating static route may have an AD of 120 or higher.
  • Backup Path:
    • It serves as a secondary or backup route, only used when the primary route fails.
  • Manual Configuration:
    • Unlike dynamic routing protocols (e.g., OSPF, EIGRP), floating static routes must be manually configured.
  • Used for Redundancy:
    • Ensures network availability by providing an alternative path if the main route goes down.
  • Remains Inactive Until Needed:
    • The floating static route does not appear in the routing table unless the primary route fails.

    How Floating Static Routes Work?

    To understand how floating static routes function, consider the following example:

    Scenario:

    • A router has two possible paths to reach a destination network:
      • Primary Route: Learned via OSPF (AD = 110).
      • Backup Route: A manually configured static route with an AD of 150.

    Process:

    1. Under normal conditions, the router uses the OSPF route because it has a lower AD.
    2. If the OSPF route fails (e.g., due to a link failure), the router checks for alternative routes.
    3. Since the floating static route has a higher AD, it was previously ignored. However, now that the primary route is unavailable, the floating static route becomes active.
    4. Traffic is rerouted through the backup path until the primary route is restored.

    Configuring a Floating Static Route in Cisco IOS

    Here’s a step-by-step configuration example:

    Topology:

    • Router R1 is connected to two networks:
      • Primary Path: Via OSPF (FastEthernet0/0).
      • Backup Path: A static route through Serial0/0/0.

    Configuration Steps:

    1. Configure the Primary Dynamic Route (OSPF):

    R1(config)# router ospf 1

    R1(config-router)# network 192.168.1.0 0.0.0.255 area 0

    R1(config-router)# exit

    1. Configure the Floating Static Route:

    R1(config)# ip route 192.168.2.0 255.255.255.0 10.0.0.2 150

    • Here, 150 is the AD, making this route "float" as a backup.
  • Verify the Routing Table:
  • R1# show ip route

    • Initially, only the OSPF route appears.
    • If the OSPF route fails, the floating static route activates.

    Why Floating Static Routes Are Important for the CCNA 200-301 Exam?

    The CCNA 200-301 exam tests your knowledge of IP routing, including static and dynamic routing concepts. Understanding floating static routes is crucial because:

    1. Redundancy & High Availability:
    • Ensures networks remain operational even if a primary link fails.
  • Cost-Effective Backup Solution:
    • Unlike dynamic routing protocols, floating static routes do not consume additional bandwidth.
  • Exam Relevance:
    • The CCNA exam may include simulation questions where you must configure or troubleshoot floating static routes.
  • Real-World Networking:
    • Many enterprises use floating static routes as a failover mechanism for critical networks.
