Hi,
The command "ip netns exec qrouter-fd907599-60a2-4efa-9c7e-65fb8c8b0f77 ip
addr" shows:
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

So only one interface is shown which is also DOWN.
BTW, I had changed the default security setting to port 22 for TCP and -1
for ICMP based on the guide given somewhere in Openstack documentation.
