Hi Taha, I haven't investigate the further though... If simple_switch_stp_13 can work on the Flow Table 0 and then rest_router can work on the Table 1, they can work together, but we need to implement them to do so.
BTW, if you just need to avoid the topology loop, how about using the STP features of switch side? OVS can handle the STP with "stp_enable" option for its Bridge and Port. Thanks, Iwase On 2017年11月22日 01:35, Taha Khan wrote:
Hi Iwase, Thanks for the reply. But Sometimes i was able to ping the interfaces two hops away from source but later it fades away. Also, I was not able to see the routes set but only addresses using the API call(/8080/router/0000000000000001). I also doubt the conflict because stp is layer 2 whereas rest_router is layer3, hence I assume they should act independently. Although, if that’s the case what could be the alternative?

Hi Taha, I guess simple_switch_stp_13 and rest_router cannot work together because these apps are just sample applications for Ryu-Book (http://osrg.github.io/ryu-book/en/html/index.html <http://osrg.github.io/ryu-book/en/html/index.html>). For example, rest_router assumes packets should be process in the pipeline, but does not aware of the flow entries of the other applications and might conflict with each other.
