Configuration procedure
The configuration on a 6to4 relay router is the same as that on an ordinary 6to4
router. However, a 6to4 relay router can be connected to not only a 6to4 network,
but also an IPv6 network.
In order for the 6to4 network connecting Router A to communicate with the IPv6
network connecting Router B, you need to configure a static route on Router A
and specify the next-hop address for the static route as the address of the
interface tunnel 0 of the 6to4 router.
Configuration on Router A
■
# Enable the IPv6 forwarding function.
<RouterA> system-view
[RouterA] ipv6
# Configure an IPv4 address for Ethernet1/0.
[RouterA] interface ethernet 1/0
[RouterA-Ethernet1/0] ip address 2.1.1.1 255.255.255.0
[RouterA-Ethernet1/0] quit
# Configure a route from Ethernet1/0 of Router A to Ethernet1/0 of Router B.
(Here the next-hop address of the static route is represented by [nexthop]. In
practice, you should configure the real next-hop address according to the
network.)
[RouterA] ip route-static 6.1.1.1 24 [nexthop]
# Configure a 6to4 address for Ethernet 1/1.
[RouterA] interface Ethernet 1/1
[RouterA-Ethernet1/1] ipv6 address 2002:0201:0101:1::1/64
[RouterA-Ethernet1/1] quit
# Configure a 6to4 tunnel.
