9.3.2 Enabling IPv6 Packet Forwarding Capability

You can perform other IPv6 configurations on an interface only when IPv6 is enabled in the
interface view. To enable IPv6 packet forwarding on an interface, you must configure IPv6 in
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
l
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ipv6
The IPv6 packet forwarding capability is enabled.
By default, the IPv6 packet forwarding capability is disabled.
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 you enable IPv6 on the interface.
Step 3 Run:
interface interface-type interface-number
The view of the VLANIF,LookBack,Tunnel or otherinterface to be enabled with the IPv6
capability is displayed.
Step 4 Run:
ipv6 enable
The IPv6 capability is enabled on the interface.
Before performing IPv6 configurations in the interface view, you must enable the IPv6 capability
in the interface view.
By default, the IPv6 capability is disabled on the interface.

9.3.3 Configuring an IPv6 Link-Local Address for an Interface

The local address of a link is used in the neighbor discovery protocol, and in the communications
between nodes on the local end of the link in stateless address auto-configuration. The local
address of a link is valid only for the link. A packet with a link-local address as the source or
destination address is forwarded only along the local link.
Issue 01 (2012-03-15)
If you run the ipv6 command only in the system view, only the IPv6 packet forwarding
capability is enabled on a device. The IPv6 function, however, is not enabled on the interface
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. Therefore, the device cannot forward IPv6 data.
