Hi guys,
I have had time to figure what is wrong on me setup. I receive an Internet feed via two gigabit interfaces. The provide offer me a dual home setup where the managed the routing (BGP4). Their way to provide an unique path is via VRRP. Me provide is using Extreme X450s switches at his end and on our side we are using Cisco Catalyst 4948.
Here is me port configuration:
sw1:
spanning-tree mode pvst
spanning-tree portfast default
spanning-tree portfast bpduguard default
spanning-tree extend system-id
no spanning-tree vlan 101
spanning-tree vlan 102,107 priority 16384
spanning-tree vlan 103 priority 8192
!
vlan internal allocation policy ascending
!
interface Port-channel22
description to-sw2
switchport trunk encapsulation dot1q
switchport trunk native vlan 155
switchport mode dynamic desirable
!
interface GigabitEthernet1/0/47
description to-sw2

Me provider is saying that we don't send BPDU and that it is require for his setup to block a port. Do you have an idea how could I resolve this issue?
Here is the show spanning-tree detail for each interface:
SW1:
Port 50 (GigabitEthernet1/0/50) of VLAN0155 is forwarding
Port path cost 4, Port priority 128, Port Identifier 128.50.
