Can I prevent VPLS loop?

From diagram all PEs are 7609 except PE4 is ASR9k. When the layer 2 of PE4 loop, I found it effected to the others PEs.

 

PE4 configuration:

#sho run l2vpn xconnect group WiFi p2p Ii

Mon Jun  8 12:01:48.676

l2vpn

 xconnect group WiFi

  p2p Ii

   interface TenGigE0/0/0/3.783

   neighbor 10.5.80.88 pw-id 1550308814 <- PE3

 

PE3 configuration:

#sho run | section l2 vfi Ft manual

l2 vfi Ft manual

 vpn id 783

 neighbor 10.5.80.3 15503088 encapsulation mpls no-split-horizon <- PE4

 neighbor 10.5.80.6 14406088 encapsulation mpls no-split-horizon

 neighbor 10.5.170.88 17588088 encapsulation mpls

 neighbor 10.5.0.88 15188088 encapsulation mpls <- PE7

 

How should I do?

 

Thank you very much.

Now, I have a solution is change to configure on ASR9k instead.

 

Thank you very much.

What is the solution on ASR9k?
