[Openstack] [netvirt-dev] VM as a router with ODL/OpenStack
Thank you - I will try this and see how it works.

On the router VM, you would probably dedicate a port for management with a floating ip assigned.
The you would have extra ports for as many nets the router is servicing, two in the case of trex simple setup. These ports would have port security disabled:
openstack port set <port> --no-security-group --disable-port-security
If running trex in the cloud vm, more less the same. Have one port for management. Then two other ports for trex traffic. On these ports, add allowed address pairs for 184.108.40.206/8 and 220.127.116.11/8 respectively
openstack port set <port> --allowed-address ip-address=18.104.22.168/8
If you have any routers in the middle, add static routes.
Not actually tried with ODL, but this works with neutron ovs driver.

Iâ??m trying to use a VM as a router in an OpenStack + ODL installation.
I have the VM set up with two internal addresses - 10.10.5.21 and
10.10.6.21. They are allocated floating public addresses of
10.201.81.21 and 10.201.82.21 respectively.
I am using a TREx load generator which sources from 22.214.171.124/8 and
sinks to 126.96.36.199/8.
I have added routes both ways on the routers between the floating and private addresses.
I have read that I need to disable â??port securityâ?? on the VM ports to allow IP spoofing - does this also include the router ports?
Also, when I start a test session generating traffic from 188.8.131.52 -> 184.108.40.206. I see a flow in OVS which matches but has an action of â??drop.â??
How do I overcome this?
Thanks in advance
