Local refers to the router itself, connected or static. The rules says same prefix learned from iBGP neighbor must be learned from IGP as well. Here is the reason of the rule. Consider you have R1-R2-R3, R1 and R3 are iBGP neighbor, all three routers are running OSPF as IGP. R3 learns route 10/8 from R1, but not via OSPF from R2 because R1 is not redistributing BGP into OSPF. In this case, if R3 forwards traffic in 10/8 to R2, it will be discarded on R2, because IGP doesn't have the route.
if I see a route in the routing table and I also see the exact same route in the BGP forwarding table, it means that route is synchronized. Correct?
More precisely: If I see a route learned via an IGP protocol (RIP, EIGRP, OSPF, ISIS) in my routing table, and I also see the exact same route in the BGP database learned from an internal BGP neighbor, the route is synchronized.
