Vignesh,
The typical openstack configuration uses a neutron network owned by the
admin which is set as external. Tenants can then allocate floating-ip
addresses from a pool associated with that network or use source-nat
(this is configured by creating a neutron router object and then
configuring that router object as a gateway "neutron router set-gateway").
The external network must have connectivity to the outside world. When
using the contrail plugin, there are two ways to do this:
- For low throughput rates, the software gateway configuration. You
can find instructions in the wiki here:
https://github.com/Juniper/contrail-controller/wiki/Simple-Gateway
- For high throughput (e.g. >10G) use an appliance that supports BGP
L3VPN and MPLS over GRE or MPLS over UDP. This is supported by all
router vendors (that i'm aware off).

Hi Team,
We have launched guest VM with updated nova.conf by running contrail
binary and also we are able to ping the other network in the same
domain, but we were not able to access internet from the guest VM. We
tried couple of stuffs but it didnt help us. Can anyone help us
regarding this..?
Thanks,
