Looking for some advice here.

Currently we have a HUB site and 2 remote sites.  All three sites are currently equipped with PowerConnect 6224 3-layer switches.  These are all connected together through an MPLS connection.  Now here is where my problem resides:

Currently I have set the network up to use 6 different VLANS.  Which all works great as far as connectivity is concerned.  My problem is that with our MPLS connections we are limited to the amount of MAC's that can be on the connection at a time.  So I basically need true 3 layer routing at each remote site.  How would I communicate between the different sites / VLANS?

All servers are located at the HUB site, so I would still need the remote sites to be able to access the servers...

Right now I have a trunk that all the vlans are routed through but I am getting individual MAC's so some connections are getting dropped once I hit the MAC limit.

Any thoughts are welcomed.
