• Sign up for lab files to use with Packet Tracer.
• Recommendations for Boson's NetSim for enhanced lab practice.

Floating Static Routes Lab

Overview

• Focus on configuring floating static routes on R1 and R2 to serve as backup routes.
• Concept: Floating static routes have a higher administrative distance (AD) than dynamic routes, making them less preferred unless necessary.

Network Setup

• Two LANs: 10.0.1.0/24 (R1) and 10.0.2.0/24 (R2).
• Direct connection via fiber optic between R1 and R2.
• Internet connections through ISP A and ISP B.

Lab Objectives

• Configure R1 and R2 to allow PC1 to reach SRV1 even if the direct link fails.
• Use ISP A as an alternative path if the direct link fails.

Steps

1. Check R1 Routing Table

   • Default route to ISP B and OSPF route to 10.0.2.0/24.
   • OSPF (AD: 110) used as the Interior Gateway Protocol (IGP).

2. Verify Routing with Simulation

   • Ping tests from PC1 to SRV1 and remote server.
   • Use simulation mode to track traffic path.

3. Configure Floating Static Routes

   • R1: IP ROUTE 10.0.2.0 255.255.255.0 203.0.113.1 111
   • R2: IP ROUTE 10.0.1.0 255.255.255.0 203.0.113.5 111
   • Verified by shutting down interfaces and checking route tables.

4. Use Traceroute Tool

   • TRACEROUTE 10.0.2.1 in Cisco IOS.
   • Useful for troubleshooting and ensuring traffic path.

Boson NetSim Lab Overview

Lab Objective

• Configure Router1 and Router2 with static routes to ensure network connectivity.
• Practice lab for static routing, with future OSPF lessons.

Key Commands

• Router Configuration
  • ENABLE, CONF T, HOSTNAME, IP ROUTE
• Interface Configuration
  • Assign IP addresses, NO SHUTDOWN
  • Configure serial interfaces with CLOCK RATE.

Verification

• Use SHOW IP ROUTE to verify configurations.
• Ping tests from Host A to Host B.
• Use Boson NetSim grading function to validate lab completion.

Conclusion

• Encouragement to use Boson NetSim for comprehensive CCNA practice.
• Acknowledgment of JCNP-level channel members for support.
• Final call to action for subscriptions, likes, and shares.
