6to4 relay configuration example
Network requirements
As shown in Figure 102, 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 an 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.
Figure 102 Network diagram
Configuration procedure
Make sure Router A and Router B can reach each other through IPv4.
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.
<RouterA> system-view
[RouterA] ipv6
# Specify an IPv4 address for GigabitEthernet 2/0/2.
[RouterA] interface gigabitethernet 2/0/2
[RouterA-GigabitEthernet2/0/2] ip address 2.1.1.1 255.255.255.0
