EX 4200, 3200 switches participating in Provider RSTP

I have a QinQ network where it basicly forms a triangle 2 parts of the triangle are a Ceragon product, and the 3rd is a juniper EX4200.  I am trying to congure RSTP on them.  The problem is that the Ceragon and the Juniper will not communicate their BPDU frames to each other.  The reason (I beleive) is that the Ceragons are sending their BPDU to 01:80:c2:00:00:08  while the Juniper is sending it to 01:80:c2:00:00:00.

After some searching I found this command:

bpdu-destination-mac-address provider-bridge-group;

but it doesent exist on the Juniper 4200.  Is it not supported on this switch?  I have tried the feature explorer but its no help.
