Hi
Let me share additional information as Packet capture.
As a result:
In spite of receiving two BGP UPDATE messages in BGPSpeaker, BMPStation has
received seven BMPRouteMonitoring messages.

Hi, Tsuboi-san
I've reproduced the problem and sent a patch to fix this.
Could you check it?
Thanks

Hi,Team
I’ve found the issue in bmp.py.
In spite of receiving a update message from eBGP router, Ryu BMP client can’t send
"Route Monitoring messages” of ADJ-RIBs-in
to BMP server,
It looks BMP client always send "Route Monitoring messages” of ADJ-RIBs-out.
Therefore, BMP Server can’t understand the next-hop as peering eBGP router, in
case of next-hop-self mode in BGPSpeaker.
Could you please fix this issue in bmp.py.
Best regards.
