Configuring Routing 583TunnelsThe PowerConnect 8024/8024F switches support the creation, deletion, and management of tunnelinterfaces. These are dynamic interfaces that are created and deleted through user-configuration. Eachswitch also supports the functionality of a 6to4 border router that connects a 6to4 site to a 6to4 domain.It sends and receives tunneled traffic from routers in a 6to4 domain that includes other 6to4 borderrouters and 6to4 relay routers.There are two classes of tunnels that facilitate the transition of IPv4 networks to IPv6 networks:configured and automatic. The distinction is that configured tunnels are explicitly configured with adestination or endpoint of the tunnel. Automatic tunnels, in contrast, infer the endpoint of the tunnelfrom the destination address of packets routed into the tunnel.The PowerConnect 8024/8024F supports point-to-point tunnels. Point-to-point interfaces provide forrouting based only on the interface (an explicit next-hop address need not be specified), and allow forthe definition of unnumbered interfaces.The Tunnels menu page contains links to web pages that configure and display tunnel parameters anddata.
