Proto-41 or 6to4 is a point-to-point tunnels in any case. So if you want
to communicate directly to the significant part of the world this way,
you need to set up and maintain hundreds of tunnels, as well as hundreds
of BGP sessions. Also you have to go through a long and hard
administrative work to negotiate all those tunnels.

In our case, you need to set up only one tunnel and only one BGP session
to the ROUTE SERVER, which provide you all the routing information about
all the peers and prefixes.
