So if a route is in the route table as static, BGP will not advertise route.
It has to be RIP, EIGRP, OSPF, etc or no sync.
Is that what we are finding ?

I correction. I tried this in the lab. I had 2 BGP routers in AS 51. They
were using 150.100.X.X as the IGP. Router A was announcing network 10.0.0.0
(loop 0 10.1.1.1). Router B had a static route 10.0.0.0 /24 150.100.1.1 .
Router B was redist BGP into RIP Domain. Sho ip bgp on Router B sho the
10.0.0.0 as valid and active and synced. Router B was NOT redistributing
10.0.0.0.
I removed the static route and added no sync to both BGP routers and the
route
was redistributed into the RIP domain.
