Cisco CCNP Certification: BSCI Exam Tutorial on Floating Static Routes
Overview
If you're familiar with static routing, you might wonder what floating static routes are. Chris Bryant, CCIE
12933, breaks down this important topic for the CCNP exam.
Deepening Your Networking Knowledge
Achieving your CCNP certification through the BSCI exam means expanding significantly on the networking skills you developed for your CCNA. While you covered static and default static routing for the CCNA, there’s more to learn, especially about floating static routes.
Understanding Floating Static Routes
A floating static route is like a backup or "floating" in your routing table. It only comes into play if routes with a lower administrative distance (AD) for the same destination are removed. For instance, if you're using an OSPF-discovered route as the primary route, a floating static route can serve as a backup if the OSPF route is absent.
Configuring Floating Static Routes
OSPF routes have an administrative distance of 110, whereas static routes typically have an AD of 1 or 0. To configure a floating static route, you must give it an AD higher than the primary route. For example, you can set a static route with an AD of 111 using the "distance" option in the "ip route" command:
```plaintext
R1(config)
ip route 110.1.1.0 255.255.255.0 172.12.123.1 111
```Here, if the OSPF route for 110.1.1.0 /24 is active, it will be preferred. The floating static route will only be used if the OSPF route is removed.
Practical Applications
Understanding floating static routes is not only crucial for passing the BSCI exam and achieving CCNP certification, but it's also valuable for real-world networking scenarios. Knowing how to configure and use these routes effectively can enhance network reliability and resilience.
By mastering floating static routes, you'll be better prepared for both your exams and practical networking challenges.
