I would need neutron.conf and l2gw_plugin.ini to check your configuration.

This problem arises when mentioning configuration twice:

service_provider=L2GW:l2gw:networking_l2gw.services.l2gateway.service_drivers.rpc_l2gw.L2gwRpcDriver:default

This could happen if you list the configuration in neutron.conf and include l2gw_plugin.ini in the startup arguments as well (cheerios for Mike Oliveras who mentioned this in an email to me).

This is more a configuration issue so this bug could be closed, I guess.

Thanks Kees,
I verified that having the service_provider line twice can cause this issue, I close this.

Changed in networking-l2gw:

Hi Lajos,

Very well and thank you again. I didn't have the time to validate and
try out the other patch.

If I do I'll obviously report back.

Regards,
Kees
