See attached diagram diagram of lab topology.
So OSPF 100 routes/interfaces communicate fine with BGP 65001, and likewise between EIGRP100 and BGP65000.
But routes from OSPF and EIGRP are not being shared through the 2 BGP Autonomous Systems meaning nothing from EIGRP 100 can ping anything from OSPF 100 and vise versa. The 2 BGP AS communicate just fine.
I just have basic BGP configs and know I am missing something just not sure what - see below.

Ok looks like one I added the actual network statements of the connecting interface subnets under BGP everything works! Thanks everyone!
