Open Stack

Hi guys,

I have installed juno openstack installation on Ubuntu 14.04. After
creating the router through neutron API with two interface , I am NOT able
to ping my external network. Router's external interface/gateway status is
DOWN.



*I am adding my content of /etc/neutron/plugins/ml2/ml2_conf.ini of the
network node:*[ml2]
type_drivers=flat,gre
tenant_network_types=gre
mechanism_drivers=openvswitch

[ml2_type_flat]
flat_networks=External

[ml2_type_vlan]

[ml2_type_gre]
tunnel_id_ranges=1:1000

[ml2_type_vxlan]

[securitygroup]
firewall_driver=neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_ipset=True
enable_security_group=True

[ovs]
bridge_mappings=External:br-ex
enable_tunneling=True
local_ip=10.20.20.52

[agent]
tunnel_types=gre




*The content of /etc/neutron/l3_agent.ini of the network node[*DEFAULT]
verbose=True
router_delete_namespaces=True
interface_driver=neutron.agent.linux.interface.OVSInterfaceDriver

*External network added by following commands:*neutron net-create ext-net
--router:external True --provider:physical_network External
--provider:network_type flat

neutron subnet-create ext-net --name ext-subnet --allocation-pool
start=10.1.166.101,end=10.1.166.200 --disable-dhcp --gateway 10.1.0.1
10.1.0.0/16


*Any help please *??
