15.6.1 Packet Tracer – Configure IPv4 and IPv6 Static and Default Routes – Instructions Answer

Introduction

Cisco's Packet Tracer is an essential tool for network engineers preparing for certifications like CCNA, CCDA, CCENT, CCNA Security, and CCNA Wireless. One of the critical topics in the CCNA 200-301 exam is configuring IPv4 and IPv6 static and default routes. This guide provides a detailed walkthrough of 15.6.1 Packet Tracer – Configure IPv4 and IPv6 Static and Default Routes, ensuring you understand the concepts and can apply them in real-world scenarios.

Understanding Static and Default Routes

What Are Static Routes?

Static routes are manually configured routes that define a specific path for network traffic. Unlike dynamic routing protocols (e.g., OSPF, EIGRP), static routes do not adapt to network changes automatically.

Advantages of Static Routes:

Low CPU & Bandwidth Usage (No routing protocol overhead)
Predictable Traffic Paths (Useful for security policies)
Simple Configuration (Ideal for small networks)

Disadvantages of Static Routes:

Manual Updates Required (Not scalable for large networks)
No Fault Tolerance (If a link fails, traffic won’t reroute automatically)

What Are Default Routes?

A default route (0.0.0.0/0 for IPv4 or ::/0 for IPv6) acts as a "catch-all" path for traffic with no specific route in the routing table. It is commonly used in:

Stub networks (where only one exit path exists)
Edge routers connecting to the internet

IPv4 Static Route Configuration

Lab Objective

In Packet Tracer 15.6.1, you will configure IPv4 static routes to ensure connectivity between different subnets.

Step-by-Step Configuration

Topology Setup

Router0 (R1) – Connected to LAN (192.168.1.0/24) and another router (10.0.0.2/30)
Router1 (R2) – Connected to LAN (192.168.2.0/24) and R1 (10.0.0.1/30)

Commands for IPv4 Static Route

On R1:

enable  
configure terminal  
ip route 192.168.2.0 255.255.255.0 10.0.0.2

(This command tells R1 to send traffic for 192.168.2.0/24 via R2 at 10.0.0.2.)

On R2:

enable  
configure terminal  
ip route 192.168.1.0 255.255.255.0 10.0.0.1

(This command tells R2 to send traffic for 192.168.1.0/24 via R1 at 10.0.0.1.)

Verification

Use show ip route to confirm the static routes are in the routing table.
Ping from a PC in 192.168.1.0 to a PC in 192.168.2.0 to test connectivity.

IPv6 Static Route Configuration

Lab Objective

Configure IPv6 static routes to allow communication between IPv6-enabled networks.

Step-by-Step Configuration

Topology Setup

Router0 (R1) – Connected to LAN (2001:DB8:1::/64) and another router (2001:DB8:A::2/64)
Router1 (R2) – Connected to LAN (2001:DB8:2::/64) and R1 (2001:DB8:A::1/64)

Commands for IPv6 Static Route

On R1:
```
enable  
configure terminal  
ipv6 route 2001:DB8:2::/64 2001:DB8:A::2  
```
(This command tells R1 to forward IPv6 traffic for 2001:DB8:2::/64 via R2 at 2001:DB8:A::2.)
On R2:
```
enable  
configure terminal  
ipv6 route 2001:DB8:1::/64 2001:DB8:A::1  
```
(This command tells R2 to forward IPv6 traffic for 2001:DB8:1::/64 via R1 at 2001:DB8:A::1.)

Verification

Use show ipv6 route to confirm the routes.
Test connectivity using ping between IPv6 hosts.

Default Route Configuration (IPv4 & IPv6)

IPv4 Default Route

A default route sends all non-specified traffic to a next-hop router (e.g., an ISP gateway).

Command:

ip route 0.0.0.0 0.0.0.0 [next-hop-IP | exit-interface]

Example:

ip route 0.0.0.0 0.0.0.0 203.0.113.1

IPv6 Default Route

Similar to IPv4, but uses ::/0.

Command:

ipv6 route ::/0 [next-hop-IPv6 | exit-interface]

Example:

ipv6 route ::/0 2001:DB8:A::1

Verification and Troubleshooting

Key Verification Commands

Command	Purpose
`show ip route`	Displays IPv4 routing table
`show ipv6 route`	Displays IPv6 routing table
`ping`	Tests connectivity
`traceroute`	Checks the path taken by packets

Common Issues & Fixes

Route Not in Table? → Check syntax and next-hop reachability.
Ping Fails? → Verify interface status (show ip interface brief).
IPv6 Not Working? → Ensure IPv6 is enabled (ipv6 unicast-routing).
