Hi All,

I have integrated OpenStack with OpenDaylight but currently it uses two NICs but my project requires the compute node to use minimum 4 NICs to make the network more independent. Does OpensStack support Mulit NICs?

Kind Regards, Rahulan

I don't know about ODL, but in principle yes. For example, see the config parameters physical_interface_mappings and bridge_mapping, which map provider networks to physical interfaces.

Thank you for the reply and yes, I understands that I can modify the ML2 to make the multi NICs works. However, when I stack the devstack, the ml2 ini get updated as default vlaues. I just need to understand that how to pass those parameter from local.conf?

Kind Rahu

If your problem is modifying the default devstack configuration, have a look at the post-config section in local.conf.

[[post-config|/$Q_PLUGIN_CONF_FILE]]
[ml2]
whatever you want to change

Let me recommend the devstack doc and Assaf Muller's devstack config.
