Hi, Today, I reinstalled openstack juno in a single node followed by Quickstart with existing network. I launched an instance successfully. But when I try to associate a floating-ip to this instance, it says no ports available! image description And I found that the interface of the external network of router 's status is "DOWN". I don't know does this matter. I try to associate floating-ip in command line. Here is the process:

[root@juno1 ~(keystone_demo)]# neutron floatingip-list 
| id                                   | fixed_ip_address | floating_ip_address | port_id |

[root@juno1 ~(keystone_demo)]# neutron floatingip-associate --fixed-ip-address e0350ad6-3400-4a1b-8f0f-03f2bb8e3e5a  2ced10e9-c49b-40fe-8f9b-85103c9c395c
Associated floating IP e0350ad6-3400-4a1b-8f0f-03f2bb8e3e5a

This make the fixed ip and floating ip mapped. However, I can not ping to the actual floating ip. That results in the host is unreachable. I don't know what's wrong with my installation. Bellow is the steps I do to create the public and private network. (my ip is, gateway is

neutron router-gateway-clear router1
neutron subnet-delete public_subnet
neutron net-delete public
neutron router-interface-delete router1 private_subnet
neutron subnet-delete private_subnet
neutron net-delete private
neutron router-delete router1

neutron router-create router1
neutron net-create private
neutron subnet-create --name private_subnet private --allocation-pool start=,end=
neutron router-interface-add router1 private_subnet

neutron net-create public --router:external=True
neutron subnet-create public --name public_subnet --enable_dhcp=False --allocation-pool start=,end= --gateway=
neutron router-gateway-set router1 public

Is there something wrong under my network creation?

Sorry, I have solved this problem.I should recreate the private net in the demo user. But a new problem happens, I can not connected to the floating ips. When i ping it, shows host unreachable.

check if your security groups are allowing icmp and ssh traffic. I have troubleshooted and reinstalled openstack multiple times without checking this.
