Jeremy’s IT Lab - CCNA IPv6 Address Configuration

Introduction

• Free, complete course for CCNA certification.
• Subscribe, like, comment, and share the videos.
• Sign up for lab files (link in description).
• Recommendation for Boson’s NetSim for CCNA (network simulator):
  • Better than Packet Tracer.
  • Includes guided labs for hands-on practice and understanding exam topics.

Lab Overview

• Objective: Simple IPv6 configuration on a network already running IPv4 (Dual-stack solution).
• Steps include enabling IPv6 routing, configuring IPv6 addresses on router interfaces and PCs, ping tests, and enabling IPv6 unicast-routing.

Steps and Commands

Step 1: Enable IPv6 Routing on R1

• Skipped initially to demonstrate the effect.

Step 2: Configure IPv6 Addresses on R1

• Commands: (enter these in CLI of R1)
  • ENABLE
  • CONF T
  • INTERFACE G0/0
  • IPV6 ADDRESS 2001:DB8:0:1::1/64
  • INTERFACE G0/1
  • IPV6 ADDRESS 2001:DB8:0:2::1/64
  • INTERFACE G0/2
  • IPV6 ADDRESS 2001:DB8:0:3::1/64

Step 3: Verify IPv6 Addresses

• Command: DO SHOW IPV6 INTERFACE BRIEF
• Check both configured and link-local addresses.

Step 4: Configure IPv6 Addresses on PCs

• PC1 Configuration: (In Config Tab)
  • Default Gateway: 2001:DB8:0:1::1
  • IPv6 Address: 2001:DB8:0:1::2/64
• PC2 Configuration: (In Config Tab)
  • Default Gateway: 2001:DB8:0:2::1
  • IPv6 Address: 2001:DB8:0:2::2/64
• PC3 Configuration: (In Config Tab)
  • Default Gateway: 2001:DB8:0:3::1
  • IPv6 Address: 2001:DB8:0:3::2/64

Step 5: Ping Tests

• PC1 Ping Tests:
  • Ping Default Gateway: PING 2001:DB8:0:1::1 (successful)
  • Ping R1's other interface: PING 2001:DB8:0:2::1 (successful)
  • Ping PC2: PING 2001:DB8:0:2::2 (failed)
• PC2 Ping Tests:
  • Ping Default Gateway: PING 2001:DB8:0:2::1 (successful)
  • Ping R1's G0/0 interface: PING 2001:DB8:0:1::1 (successful)
  • Ping PC1: PING 2001:DB8:0:1::2 (failed)

Step 6: Enable IPv6 Unicast Routing

• Command: IPV6 UNICAST-ROUTING (on R1)
• Re-confirm Ping Tests: (successful)
  • Ping PC2 from PC1: PING 2001:DB8:0:2::2
  • IPv4 Ping to PC2 from PC1: PING 192.168.2.2

Boson NetSim Lab Preview

• Boson NetSim Lab: IPv6 Configuration
• Courseware: Includes additional labs.
• Topology: IPv4 is pre-configured.
• Key Commands: IPV6 ADDRESS, IPV6 UNICAST-ROUTING
• Tasks Overview:
  • Task 1: Configure IPv6 addresses
  • Task 2: Configure IPv6 between routers

Step-by-Step Preview

• Verify Initial Configurations (IPv4):
  • Use SHOW RUN to check IP addresses.
• Enable IPv6 Packet Forwarding:
  • Command: IPV6 UNICAST-ROUTING
• Assign IPv6 Addresses to Interfaces:
  • Command: IPV6 ADDRESS <address>/<prefix_length>
  • Verify connectivity using PING IPV6 <address>

Conclusion and Acknowledgments

• Summary: Successfully configured IPv6 alongside IPv4 (dual-stack), verified with ping tests.
