6To4 Tunnel Configuration Example - HP A7500 Series Configuration Manual

6to4 tunnel configuration example

Network requirements
As shown in
(Switch A and Switch B) respectively. 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
NOTE:
Before configuring a 6to4 tunnel, make sure that Switch A and Switch B have the corresponding VLAN
interfaces created and are reachable to each other.
