6to4 relay configuration example

NOTE:

In this configuration example, either Router A or Router B is the SecPath firewall.

Network requirements

As shown in

Figure 74

, Router A is a 6to4 router, and 6to4 addresses are used on the connected IPv6

network. Router B serves as a 6to4 relay router and is connected to the IPv6 network (2001::/16).

Configure a 6to4 tunnel between Router A and Router B to make Host A and Host B reachable to each

other.

Configuration procedure

NOTE:

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

The configuration on a 6to4 relay router is similar to that on a 6to4 router. However, to enable
communication between the 6to4 network and the IPv6 network, you must configure a route to the IPv6

network on the 6to4 router.

Configure Router A:
# Enable IPv6.

system-view

[RouterA] ipv6

# Configure an IPv4 address for GigabitEthernet 0/2.

[RouterA] interface GigabitEthernet 0/2

[RouterA-GigabitEthernet0/2] ip address 2.1.1.1 255.255.255.0

[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 a 6to4 tunnel.
