Re: [Ryu-devel] How to setup multiple ASes in Mininet represented by switches in independent namespaces

Hi Takeshi, If you were to introduce a controller for each AS, how would your example be modified to achieve this?. Thanks Hadem On Mon, Mar 12, 2018 at 11:11 AM Yi Tseng wrote: > [+mininet mailing list] > > Hi, > > I think what you need to do is to create 6 network namespace and run > quagga+

Re: [Ryu-devel] How to setup multiple ASes in Mininet represented by switches in independent namespaces

Hi Can you list all listen ports inside your network namespace *r1* ? Also, I believe that the name of BGP daemon is called *bgpd* 2018-05-01 20:32 GMT+08:00 Pynbiang Hadem : > Hi Takeshi, > > I have now installed the setup environment on Ubuntu 16.04. I am still > getting the same problem. >

Hi Takeshi, I have now installed the setup environment on Ubuntu 16.04. I am still getting the same problem. I observed the following: 1) If i run: *sudo ryu-manager ryu/services/protocols/bgp/application.py --bgp-app-config-file ryu/services/protocols/bgp/bgp_sample_conf.py * inside the names

Hi Takeshi, Will your topology work only in Ubuntu 16 or will it also work in Ubuntu 14 LTS?. Presently I'm using Ubuntu 14 LTS. Thanks Hadem On Tue 17 Apr, 2018, 12:20 PM Yi Tseng, wrote: > Please use *killall* command to kill quagga daemon instead of using > *service* command > > 2018-04-13 2

Re: [Ryu-devel] How to setup multiple ASes in Mininet represented by switches in independent namespaces

Hi, You need to write the configuration for your bgp routers, I think bgp_sample_conf.py includes everything you need, all you need is to modify values in that configuration After that, you can run Ryu bgp application directly in two network namespace with two configuration. I never try Ryu BGP

Hi Takeshi, Would you mind showing some example to enter the namespace of r1. I can't seemed to figure it out. Thanks Hadem On Fri, Mar 16, 2018 at 1:15 PM, Yi Tseng wrote: > 1) > Yes, this is normal > 2) > You need to enter network namespace of r1, and use telnet to access quagga > console >

Re: [Ryu-devel] How to setup multiple ASes in Mininet represented by switches in independent namespaces

1) Yes, this is normal 2) You need to enter network namespace of r1, and use telnet to access quagga console To enter the namespace, you can use *m* command https://github.com/mininet/mininet/blob/master/util/m 2018-03-16 0:20 GMT+08:00 Pynbiang Hadem : > Hi Takeshi, > > I am able to run it now,

Re: [Ryu-devel] How to setup multiple ASes in Mininet represented by switches in independent namespaces

[+mininet mailing list] Hi, I think what you need to do is to create 6 network namespace and run quagga+zebra process inside 3 of namespace. No switch(and controller) in your topology. All you need is to install mininet and quagga(via apt-get) and enable ip forwarding on your host machine And

Re: [Ryu-devel] How to setup multiple ASes in Mininet represented by switches in independent namespaces

Hi Suresh, 1) KNet should be installed on Mininet or without Mininet?. 2) To achieve independent namespaces for each switches, do we need Quagga and Zebra?. Thanks Hadem On Sat, Mar 10, 2018 at 10:24 AM, Pynbiang Hadem wrote: > Thanks Suresh from KNet. > > I will read the documentation, try i
