Added a bash script that will emulate Openstack and OVS, so ODL can be ran ‘standalone’,

while getting events from neutron-nrothbound as well as openvswitch.

The script is located here [1] and here [2].

To work on L3 with ODL, I normally do these [3].

While the script is very much tailored to mimic the steps to create tenant … associate floatingIP,

it can hopefully be useful for other tasks you may need while testing/developing ODL.

Enjoy,

Added postman collection [1] you can use to repeat these steps.

To emulate creation of ovs ports that go with these steps, look at the description of the entries [2]:

  - Add Neutron Port For dhcp sub1

  - Add Neutron Port For vm1

Hi Mat,

In this example, I stack a single o/s node and ran the following commands: [cmds]

It will:
- create tenant, user (lines 8, 9)
- create external net for tenant (line 15)
- create external subnet (line 18)
In context of tenant, it will:
- create tenant router (line 38)
- set router gateway (line 39)
- create tenant internal net and subnet (lines 41, 42)
- create router interface on tenant internal subnet (line 43)
- boot a tenant vm (line 46)
- create floating ip and associate it with tenant vm (lines 48, 50)


A txt for neutron->odl is here [capTxt] a wireshark capture is here [capBin].
If you look at [karaf] karaf.log, you can see a lot of info on how that percolates into odl’s ovsdb netvirt.
A history of ovs commands that happened in the O/S node are here [ovsLog].

The commands used:

- capture to screen:
   sudo tcpdump -Ann -i eth1 tcp port 8080 and 'tcp[13] & 8!=0' | tee tcpdump.txt

- capture to file:
   sudo tcpdump -vv -w tcpdump.cap -i eth1 -s 0 tcp port 8080

- dump ovs history (thanks shague!):
   ovsdb-tool -mm show-log
