Huawei AR150 series - Enabling Ipv6 Packet Forwarding

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:
l Configuring the physical parameters for the interface and ensuring that the status of the
physical layer of the interface is Up
l Configuring the link layer parameters for the interface
Data Preparation
To configure IPv4/IPv6 dual stacks, you need the following data.
No. Data
1 Type and number of the interface connected with the IPv4 network
2 IPv4 address and mask of the interface connected with the IPv4 network
3 Type and number of the interface connected with the IPv6 network
4 IPv6 address and prefix of the interface connected with the IPv6 network
3.5.2 Enabling IPv6 Packet Forwarding
To enable IPv6 packet forwarding, you need to enable IPv6 in both the interface view and the
system view.
Context
To enable a device to forward IPv6 packets, you must enable the IPv6 capability in both the
system view and the interface view. This is because:
l If you run the ipv6 command only in the system view, only the IPv6 packet forwarding
capability is enabled on a device. The interface on the device is not of the IPv6 capability
and hence you cannot perform any IPv6 configurations.
l If you run the ipv6 enable command only in the interface view, the IPv6 capability is
enabled only on an interface but the device cannot forward IPv6 data.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ipv6
The IPv6 packet forwarding capability is enabled.
