Hi Sorin, This has not changed. The vRouters vhost0 interface is always bound to one (logical) interface. The logical interface can be a bond in case more bandwidth is needed. But you can still use an IXIA to inject traffic, you just need a switch which multiplexes the interface.

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.
