Hi Suresh, > 1) Routes(for extenal BGP Routers) on the RYU Host required for return traffic > to reach OF Switch. (i think, i have to add manual routing entry) Yeah, you need to install flows manually to forward ARP and BGP packets before starting Ryu BGP Speaker. This can be implemented by using

Re: [Ryu-devel] BGP Query

Hi Iwase, Yi, Thanks for the detailed explanation. Let me setup this and try. This solves some extend. But i guess, this two problems will be addressed. 1) Routes(for extenal BGP Routers) on the RYU Host required for return traffic to reach OF Switch. (i think, i have to add manual routing ent

Re: [Ryu-devel] BGP Query

Hi, I believe the high level topology which Iwase mentioned looks like: You need to config Ryu BGP speaker so Ryu BGP speaker can send BGP advertise to external BGP speaker, vice versa. For OF-Switch, you need to install flows to it so it can forward both ARP and BGP messages between Ryu BGP spe

Re: [Ryu-devel] BGP Query

Re: [Ryu-devel] BGP Query

Hi Iwase, Logically i understood . But technically i dont know how to do it. 1) BGP Speaker, Do we need to specify a configuration to connect to openflow switch?, instead of listening on a bgp port? 2) In Openflow switch, how do we configure send the packets to BGP Speaker on separate channel.

Re: [Ryu-devel] BGP Query

Hi, Just I mean Ryu BGP Speaker should connect to the OpenFlow port on OF-Switch as the same as the traditional routers. I want to describe we should not use the Controller-Switch channel to receive BGP packets (e.g. receive BGP packets via Packet-In) and should separate the link for BGP from t

Re: [Ryu-devel] BGP Query

Hi Iwase , thanks for the response. Regarding the below line, >The BGP port on Ryu is connected as a "to host" port onthe OF-Switch, I couldnot understand this point. How to configure this, and little more details about this. Can you share something more about this. Thanks Suresh. On Thu, Ma

[Ryu-devel] BGP Query

The BGP Speaker example shows that, the RYU BGP Speaker is a separate process which handles packets directly from the socket/kernel (not via Openflow encapsualtion). My use case some thing like below, In this below diagram, Tradiational BGP Router (Bird routing daemon) run BGP and connect to th
