Enabling IPv6 Packet Forwarding

Enabling IPv6 Packet Forwarding


To enable an interface to forward IPv6 packets, enable IPv6 packet forwarding in the system view and in the interface view.


  1. Run system-view

    The system view is displayed.

  2. Run ipv6

    IPv6 packet forwarding is enabled.

    By default, IPv6 packet forwarding is disabled on the device.

    To enable a device to forward IPv6 packets, enable IPv6 packet forwarding in the system view; otherwise, the device fails to forward IPv6 packets even if an IPv6 address is configured for an interface on the device.

  3. Run interface interface-type interface-number

    The view of the interface to be enabled with IPv6 is displayed.

  4. Run ipv6 enable

    The IPv6 function is enabled on the interface.

    Before performing IPv6 configurations in the interface view, enable the IPv6 function in the interface view.

    By default, the IPv6 function is disabled on an interface.
