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:

How should I do?
Thank you very much.
