IPv6 Static Routing

This lab involves configuring and troubleshooting IPv6 static routing in a simulated environment. The network consists of two routers (R1 and R2) connected via an Ethernet link, with each router having a directly connected LAN. The key challenges in this scenario include:

• Assigning proper IPv6 addresses to router interfaces.
• Configuring static routes to ensure end-to-end connectivity.
• Verifying and troubleshooting routing table issues.

Your goal is to successfully configure and verify IPv6 static routing between routers.

Objective

By completing this lab, you will:

• Configure IPv6 addresses on multiple routers.
• Establish IPv6 static routes to enable inter-network communication.
• Verify IPv6 routing table entries and connectivity.
• Troubleshoot common static routing issues.

Topology Diagram

Prerequisites

1. EVE-NG installed and operational.
2. Two IOL-L3 routers (R1, R2) and two vPCS nodes (PC1, PC2).
3. Understanding of IPv6 addressing and subnetting.
4. Familiarity with Cisco CLI and routing commands.
5. Knowledge of verification and troubleshooting techniques.

Implementation Steps

Step 1: Set Up the Topology

1. Add two IOL-L3 routers (R1, R2) and two vPCS nodes (PC1, PC2) to the EVE-NG topology.
2. Connect R1 and R2 via an Ethernet link.
3. Connect PC1 to R1 and PC2 to R2 on separate Ethernet segments.

Step 2: Configure IPv6 Addresses on R1

Assign IPv6 addresses to the interfaces of R1 to enable communication with the LAN and the link to R2.

Router>enable
Router#configure terminal
Router(config)#hostname R1

R1(config)#interface ethernet0/0
R1(config-if)#ipv6 address 2001:DB8:1::1/64
R1(config-if)#no shutdown
R1(config-if)#exit

R1(config)#interface ethernet0/1
R1(config-if)#ipv6 address 2001:DB8:2::1/64
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#

Why this step? Assigning IPv6 addresses on R1 ensures that it can communicate with both its LAN and R2.

Step 3: Configure IPv6 Addresses on R2

Assign IPv6 addresses to the interfaces of R2 to establish connectivity with the LAN and R1.

Router>enable
Router#configure terminal
Router(config)#hostname R2

R2(config)#interface ethernet0/0
R2(config-if)#ipv6 address 2001:DB8:3::1/64
R2(config-if)#no shutdown
*May 19 14:21:30.225: %LINK-3-UPDOWN: Interface Ethernet0/0, changed state to up
R2(config-if)#exit
R2(config)#interface ethernet0/1
R2(config-if)#ipv6 address 2001:DB8:2::2/64
R2(config-if)#no shutdown
*May 19 14:21:52.796: %LINK-3-UPDOWN: Interface Ethernet0/1, changed state to up
*May 19 14:21:53.796: %LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0/1, changed state to up
R2(config-if)#exit
R2(config)#

Why this step? Assigning IPv6 addresses on R2 enables communication with both R1 and its local LAN.

Step 4: Verify IPv6 on R1 and R2
