Any Example of WDS

I am taking this reference

http://support.huawei.com/ehedex/hdx.do?docid=DOC1000021724&lang=en

but I am using 2 AP (root and leaf)

but AP Leaf doesn´t register at the AC (I don´t know how could ever register if it isn´t connected to anything)

<AC6005>dis ap all
  All AP information(Normal-1,UnNormal-1):
  ------------------------------------------------------------------------------
  AP    AP                    AP              Profile   AP              AP
    /Region
  ID    Type                  MAC             ID        State           Sysname
  ------------------------------------------------------------------------------
  1     AP6010DN-AGN          00e0-fc03-ce70    0/101   normal          ap-1
  2     AP6010DN-AGN          00e0-fc03-d360    0/102   fault           ap-2
  ------------------------------------------------------------------------------
  Total number: 2

I have to connect physically AP 2 in order to register with AC, but that doesn´t make  sence since it is a remote Bridge.

Testing several times, at same moment I saw a dotted line between AP (I suppose the bridge link), but dissapeared and never came back. I attached my lab.

If there is another example for eNSP, I ´d appreciate it.

Thanks.
