Up until this point, all practical troubleshooting topics covered in this guide have been based on the current IPv4 standard. In this chapter, we are going to be looking at the same basic principles; however, the routed protocol in this case will be IP version 6 (IPv6). The TSHOOT certification exam objectives that are covered in this chapter are:
- Troubleshoot IPv6 routing
- Troubleshoot IPv6 and IPv4 interoperability
The TSHOOT certification exam requires that you not only have a solid understanding of IPv6 routing, routing protocols and IPv6 integration with IPv4 networks, but that you also understand how to support IPv6 internetworks. This includes troubleshooting IPv6 routing, routing protocols, as well as the mechanisms used to integrate IPv6 and IPv4 networks. For the most part, IPv6 routing and routing protocol troubleshooting can be performed using the methods discussed for IPv4 routing protocols.
Naturally, however, there are some differences between IPv6 and IPv4 routing protocols, with the majority of those being how they are implemented in the CLI. For this reason, this chapter will first discuss basic IPv6 routing and routing protocol configuration, as well as IPv4 and IPv6 integration mechanisms prior to discussing how to troubleshoot IPv6 internetwork problems. This chapter will be divided into the following sections:
- IP version 6 Protocol Overview and Fundamentals
- Understanding and Troubleshooting EIGRPv6
- Understanding and Troubleshooting RIPng
- Understanding and Troubleshooting OSPFv3
- Troubleshooting IPv6 Route Redistribution
- IPv4 and IPv6 Interoperability
- Troubleshooting IPv4 and IPv6 Interoperability
- Troubleshooting IPv6 Routing and Interoperability Chapter Summary
NOTE: It should be noted that this chapter will cover basic IPv6 fundamentals and principles. Additional detailed information on IPv6 can be found in the ROUTE guide which is currently available online. Please refer to that guide for additional information.
