Hello folks and Happy New Year to you!
I have an open-contrail installation on 2 physical servers - one server
running all services (control node + compute node) while the second one is only
running the nova and vrouter agent (compute node). The installation was done
from contrail-installer using devstack.
My physical server (control node) has 4 physical nics and I would like to use
all of them under VRouter control. I would also like to use them not as a bond
( port-channel) but as separate nics - to be able to inject traffic in VRouter
using ixia.
Looking into the documentation (Contrail user guide from Juniper - "Supporting
multiple interfaces on Servers and Nodes) there is a way to configure this
using fabric utility tool. Unfortunately using contrail-installer I'm not able
to get the contrail debian package used by fabric utility to deploy contrail
(contrail-install-packages-1.xx-xxx~openstack_version_all.deb)
so those instructions from the user guide are not helping me much.
I was also trying to look first in the mail achieve for a similar topic and
found an old discouraging thread ->
http://lists.opencontrail.org/pipermail/dev_lists.opencontrail.org/2013-November/000204.html
"There is a single kernel module. It can use multiple NICs. At the moment
bonding is the only supported way to have multiple data interfaces.
Virtual interfaces get their own VRFs and are isolated from each other; is
there any particular scenario that you have in mind and are trying to get to
test ?"
My hope is that this post is old enough and now this kind of topology is
supported. For example if I want to turn a server full of nics into a software
router using contrail and VRouter I will need to be able to let VRouter to
manage multiple physical nics.
In my installation I'm using the VRouter kernel module, not the dpdk support.
Thank you very much,
Sorin.
