Two root bridges VLAN1 rapid-pvst

[ALIAOF_]

I have two locations DC and Corp connected to each other via Point to Point Circuit.  I have forced the two core switches setup as GLBP pair to be primary and secondary for certain VLAN's including VLAN1.

I have a switch in our Corporate office 3750 which is where the point to point circuit terminates.  VLAN1 SVI is manually shut on that switch.  Also the priority on VLAN1 is increased manually like this, "spanning-tree vlan 1 priority 28672". 

Now the issue is that the Primarey Root Bridge in the DC is the root bridge for VLAN 1.  But this other switch 3750 in our corporate office also is a root bridge for VLAN1.  Any ideas?

CORP SWITCH:

show runn | i spanning

spanning-tree mode rapid-pvst

spanning-tree portfast bpduguard default

spanning-tree extend system-id

spanning-tree vlan 1 priority 28672

spanning-tree vlan 4,7-8,128,132,136,160,170 priority 24576

DC SWITCH:

show runn | i spanning

spanning-tree mode rapid-pvst

spanning-tree loopguard default

spanning-tree portfast bpduguard default

spanning-tree extend system-id

spanning-tree vlan 1,5,9,25,48,120,200,250 priority 24576

Yes I know that none of the switches are receiving BPDUs.  I know the BPDU guard is enabled but why rest of the VLANs are working fine then?  I have the same exact scenario setup in the lab and it works fine.

Yes these two are edge ports but each switch is the main core switch for each location.

Can u draw a high level connectivity diagram of how the three switches (two in DC) and one 3750 in corp. are connected..

Just attached the diagram to the previous post, let me know if you have any questions.

Update:  So our provider told me that they enabled tunneling on their device and after that I was able to see CDP working.  One one switch I can see that it is receving the BPDU's.  But the switch in the corporate office is still not receiving any BPDU's.
