Cabling 2 LTM's to one router

I am trying to design a setup like the one below and need some assistance on how to make the connections:

            +----------+
     +------+  Router  +-----+
     |      +----------+     |
     |                       |
     |                       |
     |                       |
     |                       |
+----------+           +-----------+
|   LTM01  +-----------+   LTM02   |
+----------+           +-----------+
     |                       |
     |                       |
     |                       |
     |                       |
     |                       |
     |    +--------------+   |
     +----+ Linux Server +---+
          +--------------+

My questions are:

1. How do I setup the connection to the upstream router?
   1. Do I tell the router is an LACP LAG or just two independent connections?
   2. Do I do anything special on the LTM's?
2. How do I setup the connection to the internal Linux server?
   1. Do I tell the server that its a LACP LAG? If not, how do I keep from getting a split route?
   2. Do I do anything special on the LTM's?

For what its worth, the Linux box has fail-open NIC's in it and will be connected to a pair of MLAG'ed switches farther down stream (LACP LAG on the Linux end).
