While the previous two tunnel mechanisms we examined were point-to-point type structures, this tunneling approach is considered a dynamic point-to-multipoint type. Since it is dynamic tunnel, we are going to do the very strange step of NOT assigning a tunnel destination as you will see. 6to4 tunnels rely on reserved address space. The reserved...
This blog series was recommended by another of our awesome students and IEOC community members, Marcio A. Costa. In the first part of this series, we will look at the Manual IPv6 tunnels that are simple to create in order to connect two "islands" of IPv6 separated by IPv4-only devices. For this blog, we will use the following simple topology:
