Step
7.
Enable DS-Lite tunneling
on the interface.
Configuration example
Network requirements
As shown in
network over the IPv6 network, perform the following tasks:
•
Configure a DS-Lite tunnel between Router A and Router B.
•
Configure NAT on GigabitEthernet 2/1/1 on the AFTR.
Figure 122 Network diagram
Configuration procedure
Make sure Router A and Router B can reach each other through IPv6.
•
Configure Router A:
# Specify an IPv4 address for GigabitEthernet 2/1/1.
<RouterA> system-view
[RouterA] interface gigabitethernet 2/1/1
[RouterA-GigabitEthernet2/1/1] ip address 10.0.0.2 255.255.255.0
[RouterA-GigabitEthernet2/1/1] quit
# Specify an IPv6 address for GigabitEthernet 2/1/2, which is the physical interface of the
tunnel.
[RouterA] interface gigabitethernet 2/1/2
[RouterA-GigabitEthernet2/1/2] ipv6 address 1::1 64
[RouterA-GigabitEthernet2/1/2] quit
# Create IPv4 over IPv6 tunnel interface Tunnel 1.
[RouterA] interface tunnel 1 mode ipv4-ipv6
# Specify an IPv4 address for the tunnel interface.
[RouterA-Tunnel1] ip address 30.1.2.1 255.255.255.0
# Specify the IP address of GigabitEthernet 2/1/2 as the source address for the tunnel interface.
[RouterA-Tunnel1] source 1::1
# Specify IP address of GigabitEthernet 2/1/2 on Router B as the destination address for the
tunnel interface.
Command
ds-lite enable
Figure
122, to enable hosts in the private IPv4 network to access the public IPv4
Remarks
By default, DS-Lite tunneling is
disabled.
Only after you use this command, the
AFTR can tunnel IPv4 packets from
the public IPv4 network to the B4
router.
