Hi,

Since the cryto maps cannot overlap, the only solution i see is to have normal hub-to-spoke connectiviy, and then between the two sopeks to create a GRE/IPSEC tunnel. The crypto map for this will be between GRE interfaces, so no static routing impediment. Over all VPNs now you add a dynamic routing protocol like EIGRP or OSPF.
