2016-09-16 13:10:48 -0500 asked a question Can we update subnet to address-scope after we created subnet manually ?

Hello

In OpenStack Mitaka is there any way to associate our manually created subnets to the address-scope ? I need to associate my subnets to some address-scope so that I can inject them into the BGP session.

Thanks

Confirmed the plugin is getting loaded successfully, but the bgp agent is not getting started. Have to manually start the bgp agent or include it into the startup script.

2016-09-15 12:33:27 -0500 asked a question Configuring BGP Agent on OpenStack using devstack

Hello

Can somebody please help me how to configure bgp_plugin and bgp_agent in OpenStack Mitaka ?

I am referrring to http://docs.openstack.org/mitaka/networking-guide/config-bgp-dynamic-routing.html (http://docs.openstack.org/mitaka/netw...) and done the setup accordingly. However, the agent is not shown in neutron agent-list output.

At /etc/neutron/neutron.conf --> I added service_plugins = router, bgp.

Since, in the above documentation it's not clear where to find bgp_dragent.ini file to configure the agent. I created it at /etc/neutron/ where the neutron.conf file is present. I added bgp_speaker_driver = neutron.services.bgp.driver.ryu.driver.RyuBgpDriver and bgp_router_id = 10.0.0.1 the interface IP of my virtual router.

I suspect maybe the bgp_router_id I am giving can be wrong too. Because, in the documentation it's written it should be the host IP running the agent. Does that mean I can not give virtual router IP address??

Please help!!

Thanks and Regards Saminder

2016-09-08 11:31:44 -0500 commented answer Ping between VMs

it should work. Can you please let me know which OpenStack version you are using? Try: neutron router-update ROUTER_UUID --router_rules type=dict list=true source=any,destination=any,action=permit

Use some routing protocol if supported by your OS version. Otherwise add static route on Router 1 for network 192.168.1.0/24 send traffic to VRouter2 and on VRouter2 add a static route to send traffic to VRouter1 for network 192.168.3.0/24 . Then, it should work.

I also found this issue. However to fix this, you should have a route for 172.24.4.23 network with proto set to kernel in the router routing table. I was missing this entry, however by adding it using sudo ip netns exec qrouter-1faa6c68-7719-4a2c-b92c-4961cac27ada ip r add 38.73.3.120/29 protocol kernel scope link via 38.73.3.121 works for me. Otherwise, OS says network unreachable while adding the entry if route is not inserted by the kernel.

Before using this command, my routing table looked like this: 2016.09.07 (Wed) 12:48:40> sudo ip netns exec qrouter-1faa6c68-7719-4a2c-b92c-4961cac27ada ip r default via 38.73.3.65 dev qg-13de1071-e6
20.0.0.0/16 dev qr-c90021cd-09 proto kernel scope link src 20.0.0.1
30.0.0.0/16 dev qr-514a3707-55 proto kernel scope link src 30.0.0.1
38.73.3.64/28 dev qg-13de1071-e6 proto kernel scope link src 38.73.3.67
38.73.3.120/29 via 38.73.3.121 dev qr-b053ed0b-43

New routing table looks like : 2016.09.07 (Wed) 12:48:40> sudo ip netns exec qrouter-1faa6c68-7719-4a2c-b92c-4961cac27ada ip r
default via 38.73.3.65 dev qg-13de1071-e6
20.0.0.0/16 dev qr-c90021cd-09 proto kernel scope link src 20.0.0.1
30.0.0.0/16 dev qr-514a3707-55 proto kernel scope link src 30.0.0.1
38.73.3.64/28 dev qg-13de1071-e6 proto kernel scope link src 38.73.3.67
38.73.3.120/29 via 38.73.3.121 dev qr-b053ed0b-43 proto kernel scope link

2016-09-07 13:59:28 -0500 asked a question Masquerading on OpenStack Router not working

Hello

I am working on a scenario where i want to implement IP masquerading on OS router specific port for the outgoing packets from a particular tenant network.

I tried sudo ip netns exec qrouter-1faa6c68-7719-4a2c-b92c-4961cac27ada iptables -t nat -A POSTROUTING -s 20.0.0.0/16 -o qr-b053ed0b-43 -j MASQUERADE where qrouter-1faa6c68-7719-4a2c-b92c-4961cac27ada is namespace value of the the OS router and qr-b053ed0b-43 is outgoing port where i want to do masquerading given by ifconfig -a output.

When i try sudo ip netns exec qrouter-1faa6c68-7719-4a2c-b92c-4961cac27ada iptables -t nat -L -v masquerading is shown for POSTROUTING. However, in reality it seems to be not working because the the packets i received at other end still have original source ip addresses.

Thanks in advance.
