In the decision making of BGP Best Path Selection; one is <<Perfer the path with lowest IGP metric to the BGP next-hop>>. Say one router (A) learns two routes from IBGP neibor ( B & C), and A_B has rip between them and A_C has OSPF between them. How will the BGP speaking router (A) decide which metric is lower to the BGP next hop.
In your scenario, Router A would use the OSPF route to get to the BGP next hop as it has a lower admin distance than RIP. The OSPF route is the one that will exist in the routing table of Router A to get to the BGP next hop. Metric comparison will come into play only when both routes belong to the same IGP.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
