Need help to configure BGP using ONOS

[Das, Souvik]

Hi,

 

I am a PhD student at The University of Texas at Dallas, and I am currently researching on Inter-domain routing and architecture proposals.

 

I am currently using ONOS as a controller in one of my labs for research work. I am hoping to set up ONOS as an active iBGP router and controller for BGP peers/speakers at the edges.

 

Till now I have tried setting up sample topologies using SDNIP app of ONOS. However, it makes ONOS act as a passive iBGP listener – means it can’t advertise routes of its own. So, it can’t redistribute routes across other BGP peers (speakers at edges). Currently, this requires creating a mesh of peerings between BGP routers. I am trying to set up a scenario where ONOS can control which routes (prefixes, ASPATHs) get redistributed across different BGP peers (speakers at edges).

 

Another issue I am facing with SDNIP is that it establishes paths using multipointtopoint intents for routes as soon as they are received by BGP peers (speakers at edges). I am trying to set up my own set of paths and need this feature disabled but I can’t find any way to configure that.

 

It would be great if someone here could address these technicalities and perhaps guide me how I could refer SDNIP to get started with and build my own app with these use-cases.

 

Regards,

Souvik

Hi all,

This is probably not the best answer you expect, but you definitely need to read most of the code on your own (takes a lot of time :( ). I am not sure how many of the original developers are still active in the forum. 

I tried to take a look at the app (I have absolutely no experience with it, though). The question about the intents might be related to this function. There are a few other functions, but cannot be totally sure which one is responsible.

Best luck!
