Hi Iwamoto & RYU Team, how are you all doing? My partner and I are still working on this Project using Ryu Controller.
We've got a question regarding *igmplib*. We got our hands on a Dijkstra implementation to determine shortest path in our SDN topology, but we're facing a big problem with igmplib: it does not behave as expected when running with *topologies that contain loops* in it. Particularly, it enters in a loop from which it cannot escape. *What are your suggestions? Is there anything that can be modified so it supports it? Are there any modifications planned in the near future?* Best regards, Lucas El mar., 5 feb. 2019 a las 22:27, IWAMOTO Toshihiro (<iwam...@valinux.co.jp>) escribió: > On Tue, 05 Feb 2019 05:36:56 +0900, > Lucas Viera wrote: > > > > [1 <text/plain; UTF-8 (quoted-printable)>] > > Hi Iwamoto & RYU Team, how are you today? > > > > Did have an opportunity to check my last email? > > > > El jue., 31 ene. 2019 a las 13:42, Lucas Viera (<lucasvier...@gmail.com > >) > > escribió: > > > > > Hi Iwamoto, thanks for your answer. > > > > > > So you think we can get similar or better functionalities using Scapy? > > > > > > We’ve encountered this suggestion in other opportunities but we were > not > > > sure about it because we’re not familiar with scapy. > > Sorry.
