Configuring a DS-Lite tunnel
A B4 tunnel interface can establish a tunnel with only one AFTR tunnel interface, but an AFTR tunnel
interface can establish tunnels with multiple B4 tunnel interfaces.
Follow these guidelines when you configure the B4 router of a DS-Lite tunnel:
•
The source addresses of local tunnels of the same tunnel mode cannot be the same.
•
The destination address specified for the tunnel interface on the B4 router must be the source
address specified for the tunnel interface on the AFTR.
•
If the destination IPv4 network is not on the same subnet as the IPv4 address of the local tunnel
interface, you must configure a route destined for the destination IPv4 network through the tunnel
interface. You can configure a static route, and specify the local tunnel interface as the egress
interface or specify the IPv6 address of the peer tunnel interface as the next hop. Alternatively, you
can enable a dynamic routing protocol on both tunnel interfaces to achieve the same purpose. For
the detailed configuration, see
Layer 3—IP Routing Configuration Guide
.
Follow these guidelines when you configure the AFTR of a DS-Lite tunnel:
•
The source addresses of local tunnels of the same tunnel mode cannot be the same.
•
Enable NAT on the interface that connects to the public IPv4 interface.
•
The tunnel destination cannot be configured on the AFTR. The AFTR uses the address of the B4
router as the IPv6 address of the tunnel destination.
•
It is not necessary to configure a route to the destination IPv4 address for forwarding packets
through the tunnel interface.
This section only covers the AFTR configuration. For information about B4 router configuration, see

Configuring an IPv4 over IPv6 manual tunnel
To configure the AFTR of a DS-Lite tunnel:

2.
Enter the view of the tunnel
interface on the AFTR.
