### Setting Up a Node with Multiple NICs
* First, configure hardware interfaces in the VPP startup config, as
described [here](https://github.com/contiv/vpp/blob/master/docs/VPP_CONFIG.md#multi-nic-configuration).
* 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.
