Hi,
> All routers are same AS number.
This means Ryu and other routers are connected with the iBGP(internal BGP)
peering, right? On the iBGP, generally the received routes from other iBGP peers
will not be advertised in order to avoid network loops. If you need to advertise
the iBGP routers to other iBGP peers, please configure Ryu as a Route Reflector
(or use different AS number on other routers for external BGP peering).
To configure route reflector, please enable "is_route_reflector_client" option.

Hi,
I am building RYU SDN BGP Speaker as transit Router. The topology is as below,
All routers are same AS number.
Traditional BGP Router1-----------------RYU BGP Speaker----------------------
Traditional BGP Router2
Here
1. RYU BGP Speaker establishes neigbors with BGP Router1 and BGP Router2.
2. RYU BGP Speaker exchanges defined routes (prefix_add ) to BGP Router1 and BGP
Router2.
3. RYU BGP Speaker learned routes from BGP Router1 and BGP Router2.
But, RYU BGP Speaker is not exchanging the routes learned from BGP Router1 to
BGP Router2 and vice versa.
How do we make it distribute routes from Router1 to Router2??? Any help is
appreciated.
I just used only below code snippet for RYU BGP Stuff
self.bgp_speaker = BGPSpeaker(local_as_number, router_id,
ssh_console=True, ssh_port=4999,
ssh_host='localhost',
best_path_change_handler=self.best_path_change_handler )
self.bgp_speaker.neighbor_add(neighbor1_id, neighbor_as_number)
self.bgp_speaker.neighbor_add(neighbor2_id, neighbor_as_number)
self.bgp_speaker.prefix_add(prefix="10.2.1.0/24 <http://10.2.1.0/24>")
