Cisco to Juniper switch p2p connectivity with failover

Hi,

We have Cisco 6506 router at H.O. and Juniper Ex switches (4300, 4200) at branch location. We are planning to connect both office with 2 point to point link. If one link goes down second link will transfer all the traffic(vlan)

please suggest how can we do that(i.e. LACP, any kind of routing(dynamic) or if any)

Thank you..
