Configuration consideration

To enable communication between 6to4 networks, configure 6to4 addresses for 6to4 routers and hosts

in the 6to4 networks.

• The IPv4 address of GigabitEthernet 0/2 on Router A is 2.1.1.1/24, and the corresponding 6to4

prefix is 2002:02 01:0101::/48 after it is translated to an IPv6 address. Assign interface Tunnel 0 to

subnet 2002:0201:0101::/64 and GigabitEthernet 0/1 to subnet 2002:0201:0101:1::/64.

• The IPv4 address of GigabitEthernet 0/2 on Router 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 GigabitEthernet 0/1 to subnet 2002:0501:0101:1::/64.

Configuration procedure

NOTE:

Before configuring a 6to4 tunnel, make sure that Router A and Router B are reachable to each other.

• Configure Router A:

# Enable IPv6.

<RouterA> system-view

[RouterA] ipv6

# Configure an IPv4 address for GigabitEthernet 0/2.

[RouterA] interface gigabitethernet 0/2

[RouterA-GigabitEthernet0/2] ip address 2.1.1.1 24

[RouterA-GigabitEthernet0/2] quit

# Configure an IPv6 address for GigabitEthernet 0/1.

[RouterA] interface gigabitethernet 0/1

[RouterA-GigabitEthernet0/1] ipv6 address 2002:0201:0101:1::1/64

[RouterA-GigabitEthernet0/1] quit

# Configure the 6to4 tunnel.

[RouterA] interface tunnel 0

[RouterA-Tunnel0] ipv6 address 2002:201:101::1/64

[RouterA-Tunnel0] source gigabitethernet 0/2

[RouterA-Tunnel0] tunnel-protocol ipv6-ipv4 6to4

[RouterA-Tunnel0] quit
