To overcome the lack of IPv6 in regional or metropolitan access networks, RENATER is deploying a tunnel broker service. The solution chosen is Hexago Migration Broker. Its main function is to connect sites or end-users who do not have IPv6 connectivity by creation of IPv6 dynamic tunnels. End-users can connect to the Tunnel Broker via a client software based on TSP (Tunnel Setup Protocol). This process will rely on MD5 authentication. The following scheme from Hexago shows the different use cases for the tunnel broker service.

The tunnel broker will also be used for bringing IPv6 connectivity to meetings, conferences or any kind of event requiring IPv6 (IST, Launch events...).
