goplane evpn/vxlan demo doesn't work well #29

Closed skjune12 closed 7 years ago

skjune12 commented 7 years ago

Hi, expert.

I try to play goplane evpn/vxlan demo - 'evpn_vxlan_test.py' on my virtual machine, but it doesn't work well.

The OS I use is Ubuntu 16.04 (xenial)

I attach an error message when I run even_vxlan_test.py below. Do you know any solution for fixing this problem?

FYI: I use Vagrant for running goplane evpn/vxlan demo. So please refer it if you need.

Please refer to this issue. https://github.com/osrg/goplane/issues/19

skjune12 commented 7 years ago

Thank you for your information. I found the reason why demo doesn't work is that there is no reachability among g1, g2, and g3. I check the interface has an IPv4 address correctly, but it doesn't work.

Could you help me?

ishidawataru commented 7 years ago

Do you have reachability to 192.168.10.1? Also, please check if any iptables rules prevent packet flows.

skjune12 commented 7 years ago

Yes, each containers can send ping to 192.168.10.1, but when I set this address as a gateway of eth0, it doesn't work too.

This is the output after I set the default gateway of eth1 to 192.168.10.1. BGP speakers have no reachability each other.

There is also a problem when I try to check the iptables rules: All container says "No such file or directory"

root@ubuntu-xenial:~# docker exec -it g3 iptables -L
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:262: starting container process caused "exec: \"/bin/iptables\": stat /bin/iptables: no such file or directory"
root@ubuntu-xenial:~# docker exec -it g3 which iptables

So I have no idea what I need to check...

ishidawataru commented 7 years ago

You don't need to exec iptables in container namespace. Instead, just run iptables -L in default namespace.

skjune12 commented 7 years ago

Sorry for that. I have no rules in my default namespace.

It seems this is causing the trouble. Please run iptables -P FORWARD ACCEPT
