Configuration Example - HP 3600 v2 Series Configuration Manual

Step
5. Specify the 6to4 tunnel
mode.
6. Configure a source
address or interface for
the tunnel.
7. Return to system view.
8. Enable dropping of
IPv6 packets using
IPv4-compatible IPv6
addresses.

Configuration example

Network requirements
As shown in
(Switch A and Switch B). Configure a 6to4 tunnel to make Host A and Host B reachable to each other.

Configuration consideration
To enable communication between 6to4 networks, configure 6to4 addresses for 6to4 switches and hosts
in the 6to4 networks.
The IPv4 address of VLAN-interface 100 on Switch A is 2.1.1.1/24, and the corresponding 6to4
•
prefix is 2002:0201:0101::/48 after it is translated to an IPv6 address. Assign interface Tunnel 0 to
subnet 2002:0201:0101::/64 and VLAN-interface 101 to subnet 2002:0201:0101:1::/64.
The IPv4 address of VLAN-interface 100 on Switch B is 5.1.1.1/24, and the corresponding 6to4
•
prefix is 2002:0501:0101::/48 after it is translated to an IPv6 address. Assign interface Tunnel 0 to
subnet 2002:0501:0101::/64 and VLAN-interface 101 to subnet 2002:0501:0101:1::/64.
Configuration procedure
Before configuring a 6to4 tunnel, make sure Switch A and Switch B have the corresponding VLAN
interfaces created and are reachable to each other.

Remarks
GRE over IPv4 tunnel by default.
The same tunnel mode should be
configured at both ends of the tunnel.
Otherwise, packet delivery will fail.
By default, no source address or
interface is configured for the tunnel.
