Hi there! Floating IP's are not working.I cannot ping Gateway and outside network. please help me with this issue . Following are the details. Thanks in advance.

Neutron Server loghttps://gist.github.com/harsha-hari/e...

On Controller nodeneutron.conf https://gist.github.com/harsha-hari/8...

ml2-conf.ini https://gist.github.com/harsha-hari/4...

On Compute nodeml2.conf.ini https://gist.github.com/harsha-hari/6...

Floating IP port on Dashboard

Status N/A

admin State UP

Host None

Profile None

VIF Type unbound

VIF Details None

VNIC Type normal

Steps in Launching external network

neutron net-create public --router:external True --provider:physical_network external --provider:network_type flat

neutron subnet-create public --name public-subnet --allocation-pool \ start=10.10.10.10,end=10.10.10.40 --disable-dhcp \ --gateway 10.10.10.9 10.10.10.0/24

After creating router

neutron router-gateway-set router public

port on network node to external network

auto eth0

iface eth0 inet static

address 10.10.10.6

netmask 255.255.255.0

Hi,

As far as I know you should setting an IP on the network interface on your neutron node on the external network, also have you tied the physical interface i.e eth0 to the ovs bridge - br-ex ->

i.e: ovs-vsctl show 58e4fc1f-8035-4eeb-bdb1-fe82025dbec0 Bridge br-ex Port br-ex Interface br-ex type: internal Port "eth0" Interface "eth0"

Also don't think you have to create an virtual router - just set the gateway IP on your physical layer 3 device for the external range for your subnet.

Could you share the results from

neutron net-show public

and then neutron subnet-show UUID_of_subnet
