Hi Suresh,
Hmmm... I can not yet understand why you need to setup such topology though...
You mean you need to spawn two BGP Speakers from a single Ryu application?
If you need to maintain routes separately on SDN-Rtr1/SDN-Rtr2 and need to
select the best path for each router, the per-peer local AS setting may not be
suitable.
Thanks,
Iwase

Hi Iwase,
The use case is like below,
Rtr1-------SDN-Rtr1-------Rtr2------SDN-Rtr2-----Rtr3
Rtr1, Rtr2, Rtr3 are traditional BGP Routers
SDN-Rtr1, and SDN-Rtr2 are BGP Speakers.
SDN-Rtr1(RYU Bgp speaker) connects to two neighbors Rtr1 and Rtr2.
SDN-Rtr2(RYU Bgp speaker) connects to two neighbors Rtr2 and Rtr3.
In this use case, Any possibility of running with single BGP Speaker instance?
Thanks
Suresh

Hi,
I think you need to specify the following options in order to avoid the
conflicts of listening ports.
- BGP listen host addresses (or port number)
https://github.com/osrg/ryu/blob/c29c9019ac8ab862bbc0caad7d49220f27ed0cf0/ryu/services/protocols/bgp/bgp_sample_conf.py#L51-L52

- RPC listen host address (or port number) for BGP
$ ryu-manager -h
...(snip)...
--bgp-app-rpc-host BGP-APP_RPC_HOST
IP for RPC server (default: 0.0.0.0)
--bgp-app-rpc-port BGP-APP_RPC_PORT
Port for RPC server (default: 50002)
...(snip)...
- SSH console host address (or port number) for BGP
https://github.com/osrg/ryu/blob/c29c9019ac8ab862bbc0caad7d49220f27ed0cf0/ryu/services/protocols/bgp/bgp_sample_conf.py#L400-L401

BTW, why you need to run multiple BGP Speakers at the same time? Ryu BGP
Speaker
supports per-peer AS number configuration, you can setup multiple
connections
with routers in different ASs. If this feature is sufficient for your
use-case,
it should be more appropriate than running multiple BGP Speakers.
