Hi Pynbiang,
Did you execute "sudo update-grub" command and then reboot?
The outputs of "ip a" command shows IPv6 is NOT enabled...
Thanks,

Hi Pynbiang,
Mininet does "disable IPv6" with some reason, I guess.
But on my environment, I can run Mininet with IPv6 enabled.
To revert "disable IPv6" settings;
1. Comment inserted line out from "/etc/sysctl.conf" and invoke "sysctl -p" to
take effect.

# Mininet: disable IPv6
HI Fujimoto,
Yes, i guess you are right. i have the following lines of code in
*/etc/sysctl.conf*
*# Mininet: disable IPv6*
*net.ipv6.conf.all.disable_ipv6 = 1*
*net.ipv6.conf.default.disable_ipv6 = 1*
*net.ipv6.conf.lo.disable_ipv6 = 1*
And the following code in */etc/default/grub*
Hi Pynbiang,
Excuse me for jumping in.
It's just my guess, is IPv6 disabled on your machine?
Mininet does disable IPv6 automatically on its installation.

Could you confirm the IPv6
Hi, Fujimoto
Tried with as you suggested.
sudo ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
However, the output is still the same.
what could be the issue?.
Thanks

Hi, Pynbiang
Thank you for sending your log messages!
In the messages, I've found:
Error creating socket: [Errno 13] Permission denied
So, "ryu-manager" may not have authority to use well-known port 179,
which is used for BGP protocol.
Please run your command with "sudo", that is:
sudo
Hi Fujimoto,
*Pls ignore the last mail. I have corrected the command as below as pointed
out by you in one of the other Forum blogs:*
ryu-manager ryu/services/protocols/bgp/application.py --bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
*Output:*
lzma module is not available
Hi Fujimoto,
Just to avoid any further complications, i have now executed the following
command:
*Command:*
ryu-manager --verbose --config-file
ryu/ryu/services/protocols/bgp/bgp_sample_conf.py
/home/mininet/ryu/ryu/services/protocols/bgp/application.py
*Output:*

Hi, Pynbiang
I'm sorry for that I've overlooked your reply.
I think something may be wrong with your ryu.conf, especially about IP
address or port settings.
Please check your ryu.conf, or could you let me see your ryu.conf?
Thanks,
Fujimoto

I have followed the steps given by you:

I'm running the above BGP test applications on ryu 3.30 and am getting some

Thanks Fujimoto for the insightful reply.
I will try to implement it accordingly.
Thanks

Hi, Pynbiang
FYI, you can run two Ryu BGP applications by the following steps:
1. Run mininet
$ sudo mn --switch ovsbr --topo single,2 --mac -x
2. Run applications in each host
h1> ryu-manager [application1.py] --bgp-app-config-file
[config_file_for_application1.py]

Hi, Pynbiang
I guess it is the cause of the problem that the two applications use the
same port.
Unfortunately, the port which the application uses is no configurable,
so you cannot run the two applications simultaneously in a single host.
To run the applications, I suggest the following
Hi,
I prepared two instances of the RYU BGP app as below:
1) /home/mininet/BGP1/application1.py
2) /home/mininet/BGP2/application2.py
I also made the changes to the application1.py (correspondingly for
application2.py) as below:
CONF.register_opts([
cfg.IntOpt('bind-port', default=50001,
Hi, Pynbiang.
Yes, you need to run at least 3 instances of the application for a
network with three AS.
If you want to run more BGP instances in an AS, you need to run more
instances of the application.
Thanks,
Fujimoto
