SP CISCO LAB TEST VPLS

Hi,

I wonder if you know how to fix this vpls problem. I'm doing the SP test from
Cisco

When I connect the switch back to back it works without any problem and the
spanning tree works fine I can ping each other

When I connect my service provider network through one CRS and AS9K the bridge
looks fine on my routers but then I get one of the switches SW3 on block mode
on vlan 98

SW3#sh spanning-tree vlan 98

VLAN0098
  Spanning tree enabled protocol ieee
  Root ID Priority 4194
             Address 001f.27b0.3000
             This bridge is the root
             Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec

 Bridge ID Priority 4194 (priority 4096 sys-id-ext 98)
             Address 001f.27b0.3000
