Setting Up a Node with Multiple NICs

• First, configure hardware interfaces in the VPP startup config, as described here.

• For each interface owned by Linux, you need to provide individual configuration for each interface used by VPP in the Node Configuration for thenode in the contiv-vpp.yaml. For example, if both ens3 and ens4 are known to Linux, then put the following stanza into the node's NodeConfig:

...
    NodeConfig:
    - NodeName: "ubuntu-1"
      StealInterface: "ens3"
      StealInterface: "ens4"
...

If only ens3 is known to Linux, you only put a line for ens3 into the above NodeConfig.
