# Bind a L2 VIP to Node Cluster with Keepalived
You can bind an optional L2 VIP on a node cluster with [`vip_enabled`](/docs/reference/param/#vip_enabled).

```bash
proxy:
  hosts:
    10.10.10.29: { nodename: proxy-1 }
    10.10.10.30: { nodename: proxy-2 } # , vip_role: master }
  vars:
    node_cluster: proxy
    vip_enabled: true
    vip_vrid: 128
    vip_address: 10.10.10.99
    vip_interface: eth1
```

```bash
./node.yml -l proxy -t node_vip     # enable for the first time
./node.yml -l proxy -t vip_refresh  # refresh vip config (e.g. designated master)
```
