[Bird2] Doubt about Route Server function and iBGP

Hello Guys, On bird1.6, I have deployed our Route Servers using the below architecture to split the load from the control plane: Customer1 <-> RS1[pid0] <-> iBGP <-> RS2[pid1] <-> Customer2 And is working fine as RS until now [not inserting local AS on AS-PATH and not changing NH]. I'm planing to migrate to Bird2.0.2 with some new features, but when I do the same on Bird2.0.2, I have the AS from iBGP inserted on AS-PATH, just to let me know, this is an expected behavior on Bird2? I have tested in a lot of ways, but still the same results. []s
