We are in the process of getting 6 MPLS T1s for our WAN. These T1s are to go into two 2691 routers which will also have 6 voice PRIs that will tie into a CallManager.
The two routers will have HSRP configured for the ethernet interfaces. The MPLS setup is all done through the providor so we shouldn't need to do anything special to support that.
I'm not quite sure what the ideal configuration for the routing to the WAN would be. Since we have 6 T1s, it would be nice to be able to load balance the traffic somehow through the T1s and keep a high degree of redundancy.
when it comes to load balancing the best choice will be EIGRP routing, If you are planning to run VPNs, you might need to have a discussion with your provider too. When you enable EIGRP make sure you configure maximum-paths under router configuration mode,by default its one. You can also increase the redundency by configuring serial tracking. details about EIGRP over MPLS is given in the link below:
