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.

Thanks,
