As I was doing a Vol2 workbook lab the other day I found out that even if I have learned IPv6 tunneling before I was unable to configure it properly. That is why I have decided to make a post on IPv6 tunneling and I will especially focus on the protocol 6to4 described in RFC 3056 which facilate the deployment of IPv6 over IPv4 networks through tunnels. I will also talk briefly of RIPng, EIGRPv6 and IPv6 MP-BGP.
I will first talk about some static tunnel mechanisms and then I will explore 6to4 in more details. For this topic I will use the following topology:
IGP: EIGRP AS 100
Platform/IOS: Cisco 2691/12.4(15)T11 Adv IP services
