Describe the tunneling transition to IPv6 method.
What will be an ideal response?
Tunneling is a transition method that encapsulates IPv6 traffic inside IPv4 packets. This is done when portions of a network are running IPv6 and other network areas have not been upgraded yet. Put simply, the tunnels are used to get IPv6 traffic across an IPv4 area to another IPv6 area. The greatest concern with tunneling involves security. If you manually configure the tunnels at each end, there will be less of a security issue because you will be able to monitor the traffic at the endpoints. However, the preferred tunneling technique is to use dynamic tunnels, which are automatically created based on destination address and routing parameters. The problem is that dynamic tunneling does not create interfaces that can be monitored. This makes malicious, injected traffic more likely. Because of this security issue, it is recommended that organizations use the dual stack transition method if possible.
