Router status is down when integrated with OpenDayLight

Hi there,

I am trying to integrate Opendaylight Boron with OpenStack Newton, but encouter some problems. I have followed the http://docs.opendaylight.org/en/stable-boron/submodules/netvirt/docs/openstack-guide/openstack-with-netvirt.html (OpenStack with NetVirt Docs) with three CentOS 7.1 servers.

At first, a deployment of 1 controller 1 network and 1 compute OpenStack is done, and everything works fine. (Not devstack)

Then, I install the Opendaylight odl-router on my OpenStack cloud, and make every configuration according to the previous link.

Here are some informations that may be important for you to help me:)

OpenStack Deployment:

  • Controller Node: (neutron-server)
    • neutron.conf is modified correctly
    • Opendaylight controller is started and ${CONTROLLER}:8181/index.html looks fine.
  • Network Node:
    • neutron-openvswitch-agent is shutted down
    • Open vSwitch configuration is empty and the manager is correctly set
  • Network Node: (neutron-dhcp-agent neutron-metadata-agent)
    • neutron-l3-agent is shutted down (Is it correct ? I'm not sure)
    • neutron-dhcp-agent & neutron-metadata-agent configuration is modified correctly
  • Each Node have two interfaces em1 em2. em1 for tunnel and em2 for provider network.

Opendaylight Boron version:

  • distribution-karaf-0.5.2-Boron-SR2

Open vSwitch version: (I have tested following two versions, but encountered the same problem)

  • 2.6.1
  • 2.5.0

The kernel modules releated with openvswitch looks like:

$lsmod | grep openvswitch
openvswitch           257678  4 vport_vxlan
nf_nat_ipv6            13279  1 openvswitch
nf_nat_ipv4            13263  2 openvswitch,iptable_nat
nf_defrag_ipv6         34651  2 openvswitch,nf_conntrack_ipv6
nf_defrag_ipv4         12729  2 openvswitch,nf_conntrack_ipv4
nf_nat                 21798  4 openvswitch,nf_nat_ipv4,nf_nat_ipv6,iptable_nat
nf_conntrack          101024  7 openvswitch,nf_nat,nf_nat_ipv4,nf_nat_ipv6,iptable_nat,nf_conntrack_ipv4,nf_conntrack_ipv6
gre                    13808  1 openvswitch
libcrc32c              12644  2 xfs,openvswitch

After configuring external network on Network Node, ovs-vsctl looks like:

$ovs-vsctl set Open_vSwitch . other_config:provider_mappings=provider:em2
$ovs-vsctl show
81d7f08b-80cb-45d7-a7c6-adcd58c99fe7
    Manager "tcp:10.24.84.144:6640"
        is_connected: true
    Bridge br-int
        Controller "tcp:10.24.84.144:6653"
            is_connected: true
        fail_mode: secure
        Port "em2"
            Interface "em2"
        Port br-int
            Interface br-int
                type: internal

But I got some errors in karaf.log:

Having same problem. I but it was working yesterday normally but after restart everything is messed up. On this page http://serverascode.com/2017/01/09/opendaylight-boron-openstack-networking-odl.html (link text) it says that icmp is not working(that is true i did test it yesterday and ssh was working but ping didnt). I dont see any errors anywhere but it is still not working. Try to ssh into floating ip or ssh from vm to the compute server.

I'm afraid we encountered the different case? I can ssh into controller/compute/network node from VM, but can't ssh into VM from any node. But still thanks a lot. ODL Summit 2016 PPT shows that we can ping the VMs from outside, so I just believe that and had never try to ssh from VM.

May be there are still some problems with ODL DNAT? Any other ideas?

It's pretty strange that VM can't ssh outside nodes after associated a floating IP. Life sucks..

Bugs everywhere and no answers on forums and anywhere. I feel you. I was talking with my mentor today and i think will not use ODL for my Openstack because bugs and half of the things dont work still.

Good news. Network finally works fine with version distribution-karaf-0.4.4-Boron-SR2.
