Configuration Statement

interfaces {
  loopback interface-name {
    ipv6 {
      disable

  }
}

By default, IPv6 is enabled on all interfaces. A global command exists which can disable IPv6, namely set system ipv6 disable, and this will take precedence over any of the existing per-interface based, IPv6 commands.

IPv6 Forwarding can be disabled via the set interface loopback interface-name ipv6 disable-forwarding command, but note that IPv6 traffic can still be terminated on this interface.

IPv6 configuration can be totally disabled via the set interface loopback interface-name ipv6 disable command.

Use the set form of this command to disable IPv6 on this interface.

Use the delete form of this command to enable IPv6 on this interface.

Use the show form of this command to display the current IPv6 configuration on this interface.
