Followed the openstack juno document end to end everything is fine except that I cannot ping the above address

Question which I have, eth2 which is exposed to internet, has following lines in /etc/network/interfaces

iface eth2 inet manual up ip link set dev $IFACE up down ip link set dev $IFACE down

I cannot ping openstack.org from eth2 though it is connected to internet router which is configured network node. is it normal?

my architecture looks like this

controller node connected to internet (192.168.1.x) and management network 10.0.0.x here is interfaces contents

iface eth0 inet static
    address 10.0.0.11
    netmask 255.255.255.0
iface eth1 inet static
    address 192.168.1.211
    netmask 255.255.255.0
    gateway 192.168.1.1

compute node is connected management network (10.0.0.x) and tunnel network (10.0.1.x)

iface eth0 inet static
    address 10.0.0.31
    netmask 255.255.255.0
iface eth1 inet static
    address 10.0.1.31
    netmask 255.255.255.0

Network node is connected to management network(10.0.0.x), tunnel network (10.0.1.x) and internet router

iface eth0 inet static
    address 10.0.0.21
    netmask 255.255.255.0
iface eth1 inet static
    address 10.0.1.21
    netmask 255.255.255.0
iface eth2 inet manual
    up ip link set dev $IFACE up
    down ip link set dev $IFACE down

With this architecture I am not able to ping 203.0.113.101?

is there an problem with interfaces file on on the three nodes?

Please, post ovs-vsctl show && ifconfig on network node.

Please, upload formatted text (complete) for both reports been asked && post links into thread.
I see just one and it doesn't look complete.

For some I am not able to upload the formatted text into this comments section Is there any place where I can upload the file ?

UPDATE 05/31/2015
Eth1 on Controller is not needed. Br-ex entry in /etc/network/interfaces is missing on Network Node
My final feed is in https://ask.openstack.org/en/question...
END UPDATE

On 05/21/2015  I was unable to see links, comment message was resent to me only on 05/29/2015

To route your system to Internet make interface eth2 OVS port of OVS bridge br-ex
Bridge br-ex assign IP address belongs external net. Eth2 connect to internet router
Syntax of ifcfg-br-ex && ifcfg-eth2 files I have only for RH system ( translate to ubuntu, please)

1. If my gateway of external network which can access http://openstack.org is 192.168.1.1, I should use 192.168.1xxx in place of 203.0.113.xxx, is my understanding correct?

Yes , it's correct

2. I see on compute, you have configured 172.24.4.228 as a public IP address. to which interface you assigned this IP?

That's wrong Compute doesn't have public interface at all . Only eth0 - mgmt and eth1 - VTEP's

Thanks dbaaxps, I have reading this pictorial representation for your setup. I have couple of couple questions. 1. If my gateway of external network which can access http://openstack.org is 192.168.1.1, I should use 192.168.1xxx in place of 203.0.113.xxx, is my understanding correct?

second question is in your architectural diagram, i see on compute, you have configured 172.24.4.228 as a public IP address. to which interface you assigned this IP?

Third question, on the compute node, you have IP address 192.169.142.137, to which ethernet interface you have assigned this IP address, is it for eth0 or eth1? if it is eth0 (i am assuming) then what is ip address you have assigned for eth1?

adendukuri gravatar imageadendukuri ( 2015-06-02 07:04:01 -0600 )edit

eth0 has address 192.169.142.137 on mgmt net
eth1 has address 10.0.0.137 on vtep's net
