Suffix - Configured by the user
Comparison of DS-Lite and IPIP:
n
Both DS-Lite and IPIP use an IPv6 internet connection to carry the IPv4 traffic.
n
DS-Lite – The gateway address is non-globally-routable and automatically selected from the subnet
192.0.0.0/29.
IPIP - The gateway address is globally-routable and you configure it manually.
n
In both DS-Lite and IPIP, you can get the prefix of the IPv6 address dynamically using SLAAC.
n
DS-Lite – The IPv6 address is automatically generated based on the acquired prefix and an auto-
generated suffix, based on the interface Ethernet MAC address.
IPIP - The IPv6 address must end with a manually configured suffix.
n
When the prefix of the IPv6 carrying the IPIP connection is changed, you must notify the IPIP tunnel
provider over HTTP.
The WAN connection type of the IPIP master must be
Dynamic IPv6
.
To enable IPIP:
1. Enable the IPIP feature in

AFTR address
field appears. This field shows the hostname or IPv6 address for DS-Lite/IPIP
tunnel.
Note - This field is optional when the IPv6 connection type is DHCPv6.
6. In the
Linked connection
field, select the IPv6 connection name.
This is the IPv6 Internet connection index on which the DS-Lite/IPIP tunnel is defined.
Note – The IPIP tunnel and its linked IPv6 connection must be on the same appliance port.
7. In
VNE Settings
, select
Transix
for the
Service name
.
8. In the
Advanced
tab:

.
Note – This is configured in the IPv6 connection configuration window. Otherwise, IPIP is
configured on the IPv4 connection.
b. Configure the default
MTU
of the IPIP interface to 1460 (IPv4 default = 1500). The size of the
IPv6 header is 40.
