A remote site currently has a Frame T1 with at&t in a 7200 router at the hub site. A P2P T1 is being installed from a different provider from the same remote site to the same 7200 router to upspeed the connection.OSPF is currently running on the network. questions is what is the best way to load balance both T1 ones, Is there any special configuration required for it.Any help would be appreiciated.

If there is a Frame Relay T1 and a point to point T1 originating on the same local router and terminating on the same rmote router, and if OSPF is configured on both interfaces, and if OSPF sees the same cost on both interfaces (based on both interfaces having the same bandwidth – either the default is the same on both or each is configured with the same bandwidth) then OSPF will load balance on both T1s. This is the best way to load balance: configure OSPF on both interfaces and make sure that both interfaces have the same cost. Other than that there is no special configuration.
