When ISPs tend to extend their IPv4 or MPLS networks with IPv6 traffic exchange capability
on MPLS, they only need to update their PE devices.

11.3 Configuring IPv4/IPv6 Dual Stacks

To establish an IPv6 over IPv4 tunnel, you need to configure both the IPv4 protocol suite and
the IPv6 protocol suite on the devices where an IPv4 network borders an IPv6 network.

11.3.1 Establishing the Configuration Task

This section describes the applicable environment, pre-configuration tasks, data preparation, and
configuration procedure for the IPv4/IPv6 dual protocol stack.
Applicable Environment
If a device has both IPv4 and IPv6 connections, the IPv4/IPv6 dual protocol stacks need to be
enabled on the device.
Enabling the IPv4/IPv6 dual protocol stacks on the S9300&S9300E is a simple process. Enable
the IPv6 packet forwarding capacity in the system view and configure an IPv4 address or IPv6
address on the corresponding interface. The device can then forward IPv4 and IPv6 packets on
the corresponding interface.
Pre-configuration Tasks
Before configuring IPv6 tunnels, complete the following tasks:

6PE
Router
IPv4/MPLS
CE
IPv6
site
Enable IPv4, MPLS and IPv6 on 6PE.
MP-BGP also needs to be enabled between 6PEs to receive or send IPv6 routes from/to the
remote 6PE.
The IGP over ISP's IPv4 backbone network can be OSPF or IS-IS.
Static routing protocol, IGP or EBGP can work between CE and 6PE.
