Configuring Routing 599
Tunnels
The PowerConnect 6200 Series
switches support
the creation, deletion, and management of tunnel
interfaces. These are dynamic interfaces that are created and deleted through user-configuration. Each
switch 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 border
routers and 6to4 relay routers.
There are two classes of tunnels that facilitate the transition of IPv4 networks to IPv 6 networks:
configured and automatic. The distinction is that configured tunnels are explicitly configured with a
destination or endpoint of the tunnel. Automatic tunnels, in contrast, infer the endpoint of the tunnel
from the destination address of packets routed into the tunnel.
The PowerConnect 6200 Series supports point-to-point tunnels. Point-to-point interfaces provide for
routing based only on the interface (an explicit next-hop address need not be specified), and allow for
the definition of unnumbered interfaces.
