Public bug reported:
Having a distributed router with interfaces for an internal network and
external network.
When Launching a instance and pinging an external network and then associating
a floating to the instance the connection is lost i.e.
the ping fails.
When running the ping command again - it's successful.
Version
======
RHEL 7.1
python-nova-2015.1.0-3.el7ost.noarch
python-neutron-2015.1.0-1.el7ost.noarch
How to reproduce
==============
1. Create a distributed router and attach an internal and an external network
to it.
# neutron router-create --distributed True router1
# neutron router-interface-add router1 <subnet1 id>
# neutron router-gateway-set <external network id>
2. Launch an instance and associate it with a floating IP.
# nova boot --flavor m1.small --image fedora --nic net-id=<internal network
id> vm1
3. Go to the console of the instance and run ping to an external network:
# ping 8.8.8.8
4. Associate a floating IP to the instance:
# nova floating-ip-associate vm1 <floatingip-address>
5. Verify that the ping fails.
