11.3.2 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:

Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ipv6
The IPv6 packet forwarding capability is enabled.
To enable a device to forward IPv6 packets, you must run this command in the system view;
otherwise, the device cannot forward IPv6 packets although the interface is configured with an
IPv6 address.
By default, the IPv6 packet forwarding capability is disabled.
Step 3 Run:
interface vlanif vlan-id
Issue 01 (2012-03-15)
Configuring the physical parameters for the interface and ensuring that the status of the
physical layer of the interface is Up
Configuring the link layer parameters for the interface
Data
Type and number of the interface connected with the IPv4 network
IPv4 address and mask of the interface connected with the IPv4 network
Type and number of the interface connected with the IPv6 network
IPv6 address and prefix of the interface connected with the IPv6 network
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.
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.
