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

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?
Thanks!

Subject: Re: [Ryu-devel] Setting Default Routes in custom topology.
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.
Thanks,
Iwase
