Thanks Alex for looking into this, and your tips. I have to correct myself, it
looks like prepend may work. I will try it.
Thanks,

If you prepend announces from every leaf to the spine, then
r01.l
Hello Aleksander,
Prepends does not work for me because I would prepending on every leaf so
as-path still will be the same from perespective r01.leaf108
Looks like AIGP is not for me too because we don’t have IGP inside network.
Every iBGP session is established over directly connected p2p links.
Hi Dariusz,
Will ASPATH prepends work for you?
Or this feature might help you:

Hello Bird Users,
Have a question about bgp best path algorithm in Route Refletector
environment and possible fix:
Topology ( we use only iBGP with multiply RR):
r01a.tor - r01.leaf.105---r01.spiner01.leaf108-r09a.tor
I announce the same block 172.232.0.0/19 from both tors
r01.le
