57 Tunnel Interface Commands PowerConnect provides for the creation, deletion, and management of tunnel interfaces. They are dynamic interfaces that are created and deleted by user configuration. Tunnel interfaces are used for the following purposes. • IPv4 tunnels • IPv6 tunnels Each router interface (port or VLAN interface) may have associated tunnel interfaces. Each interface can have multiple tunnel interfaces. There is no set limit to the number of tunnel interfaces associated with a router interface. There is a compile platform limitation to the number of tunnel interfaces available to the entire system. To support IPv4 to IPv6 transition, PowerConnect supports configured tunnels (RFC 4213) and automatic 6to4 tunnels (RFC 3056). 6to4 tunnels are automatically formed for IPv4 tunnels carrying IPv6 traffic. The automatic tunnels IPv4 destination address is derived from the 6to4 IPv6 address of the tunnel's next hop. PowerConnect can act as a 6to4 border router that connects a 6to4 site to a 6to4 domain. The border router sends and receives tunneled traffic from routers in the 6to4 domain that include other 6to4 border routers and 6to4 relay routers. Commands in this Chapter This chapter explains the following commands: interface tunnel show interfaces tunnel tunnel destination tunnel mode ipv6ip tunnel source - Tunnel Interface Commands 1373
