For those using Ubuntu 16.04 LTS and dibbler packages, it's necessary to
install dibbler-server and dibbler-client.

The problem was that dibbler-client was not available
(/var/log/neutron/neutron-l3-agent.log).

ERROR neutron.agent.linux.utils [-] Exit code: 99; Stdin: ; Stdout: ;
Stderr: /usr/bin/neutron-rootwrap: Unauthorized command: ip netns exec
qrouter-e6f7c217-c962-4107-a20f-e29c54366867 dibbler-client start -w
/var/lib/neutron/pd/e6f7c217-c962-4107-a20f-e29c54366867:b97828a1-79dc-42cf-92d7-d5f0fec93a56:qr-b8b30c59-17
(no filter matched)

Although error says 'unauthorized command'  the problem was not to have the
utility.

Tks.
