Thank you so much for the reply. It is clear to me now
Let’s suppose, there is no route reflector(R2) in the same topology. R2 is just like a ibgp neighbor.
In this case, does R4 and R5 exchange the ibgp routes to each other about the ip prefix 18.104.22.168/32.
Can we see 2 BGP routes. one best path as ebgp and the other ibgp route via R5.
