Neutron Network Issue. Gateway not pinging for the external network.

In Network  node

ip netns

Above command will give the virtual router's as you can see my output below. From that select the qrouter ID and try command

ip netns exec <qrouter-id> ip addr

ip netns exec <qrouter-id> route -n

The above commands should show IP's in virtual router and routing table of qrouter.

make sure your routing table shown as has a gateway. Or else try setting it using

ip netns exec <qrouter-id> route add default gw *** *** *** ***

ip netns exec <qrouter-id> iptables save
