MX has had support for PBB (and thus 802.1ah) since 10.0:

I too would like to see SPB get some support in Junos, or alternatively, JunosSDK getting some support for layer2 protocols, so someone else can have a crack at implementing it.

The pendulum of hype in the data centre appears to be swinging away from distributed control-plane and toward centralised everything (QFabric, Virtual-Chassis, SDN etc).  Maybe there is still hope for the metro?
