iBGP peering issue between Cisco N3k's

Hi all,

I am hoping you can provide some help with an iBGP peering issue. I have a customer site where there are two circuits (same carrier) for redundancy that terminate into two separate Nexus 3048s. I have eBGP configured on the uplinks and I am trying to configure iBGP between the two units. I do not have OSPF running as an IGP, just static routes for the peer subnets.
