undo ds-lite enable
Default
DS-Lite tunneling is disabled on an interface.
Views
Interface view
Predefined user roles
network-admin
Usage guidelines
Use this command on the AFTR's interface that connects to the public IPv4 network, so the AFTR can
forward IPv4 packets to the B4 router through the DS-Lite tunnel.
You cannot enable DS-Lite tunneling on a DS-Lite tunnel interface on the AFTR.
Examples
# Enable DS-Lite tunneling on interface Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet1/1
[Sysname-Ethernet1/1] ds-lite enable
encapsulation-limit
Use encapsulation-limit to set the maximum number of nested encapsulations of a packet allowed on a
tunnel interface.
Use undo encapsulation-limit to remove the configured encapsulation limit.
Syntax
encapsulation-limit number
undo encapsulation-limit
Default
There is no limit to the nested encapsulations of a packet
Views
Tunnel interface view
Predefined user roles
network-admin
Parameters
number: Specifies the number of nested encapsulations, in the range of 0 to 10.
Usage guidelines
A packet added with excessive headers becomes oversized. If it exceeds the MTU, it must be fragmented,
which decreases forwarding rate and increases processing complexity. To avoid this situation, use this
command to limit the number of encapsulations.
This command is applicable to only IPv6 over IPv6 tunnels.
