Thanks Kevin.

The router seems correctly schedule to the agent. After doing more 
tests, I realised the issue also happens when I try to link a new 
floating-ip. This is the log:
Command: ['sudo', 'neutron-rootwrap', '/etc/neutron/rootwrap.conf', 
'ip', 'netns', 'exec', 'qrouter-84a23b9d-cf74-435c-99a1-53b842209c73', 
'ip', '-4', 'addr', 'add', '192.168.7.204/32', *'brd', 'None'*, 'scope', 
'global', 'dev', 'qg-ee3cf43a-10']
Exit code: 1
Stdout: ''
Stderr: 'Error: an inet address is expected rather than "None".\n' 
execute /usr/lib/python2.7/site-packages/neutron/agent/linux/utils.py:75

I see that a broadcast address is expected, for instance

ip netns exec qrouter-84a23b9d-cf74-435c-99a1-53b842209c73 ip -4 addr 
add 192.168.7.204/32 *brd 192.168.7.255* scope global dev qg-ee3cf43a-10

I continue searching for any solution.
Miguel.
