xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch CLI Reference Guide Parameters - Enter the IP tunnel interface name used here. This name can be up to 12 characters long. ipv6address - (Optional) Specifies the IPv6 address assigned to this IPv6 tunnel interface. IPv6 processing will be enabled on this IPv6 tunnel interface as soon as its IPv6 address is configured. The 32 bits following the initial 2002::/16 prefix correspond to an IPv4 address assigned to the tunnel source. - Enter the IPv6 address used here. source - (Optional) Specifies the IPv4 source address for a packet sent to the remote end of the 6to4 tunnel. The IPv4 destination address for the packet is derived from the IPv6 destination address of the remote destination, which is in the format of a 6to4 address. The address is derived by extracting the 4-octets immediately following the IPv6 destination address's 2002::/16 prefix. For example, a 6to4 address, 2002:c0a8:0001::/48 will be extracted to 192.168.0.1. Any IPv6 address that begins with the 2002::/16 prefix is known as a 6to4 address - Enter the IPv4 source address used here. Restrictions Only Administrator, Operator and Power-User level users can issue this command. (EI Mode Only Command) Example To configure an IPv6 6to4 tunnel (Tunnel name is "tn2", Tunnel source IPv4 address is 10.0.0.1, Tunnel IPv6 address is 2002:a00:1::1/64): DGS-3620-28SC:admin# config ip_tunnel 6to4 tn2 source 10.0.0.1 Command: config ip_tunnel 6to4 tn2 source 10.0.0.1 Success. DGS-3620-28SC:admin# config ip_tunnel 6to4 tn2 ipv6address 2002:a00:1::1/64 Command: config ip_tunnel 6to4 tn2 ipv6address 2002:a00:1::1/64 Success. DGS-3620-28SC:admin# 44-5 config ip_tunnel isatap Description This command is used to configure an existing IPv6 tunnel as an IPv6 ISATAP tunnel on the switch. If this tunnel has previously been configured in another mode, the tunnel's information will still exist in the database. However, whether the tunnel's former information is valid or not will depend on the current mode. IPv6 ISATAP tunnels are point-to-multipoint tunnels that can be used to connect systems within a site. An IPv6 ISATAP address is a well-defined unicast address that includes a 64-bit unicast IPv6 prefix (it can be either link-local or global prefixes), a 32-bit value 0000:5EFE/0200:5EFE and a 32-bit tunnel source IPv4 address. 518
