Static route needed in iWAN so I can use my Point to Point circuit.

I have a large iWAN (ISR4451's) install.  I have a new P2P circuit (between 2 buildings) but I can't get my iWAN routing to obey my static route.  Below are the running configs for my switchport on my Nx9K and my 3850 switches, along with the traceroutes.  The 3850 switch will obey my static route and I can pass traffic.  My Nexus 9K switch refuses to use my static route with Metric 1.

Hello,

not really sure what your topology looks like, but why don't you configure PBR on the Nexus, as this takes precedence over everything else ?
