 Kube-OVN supports advertise pod/subnet ips to external networks by BGP protocol.
 To enable BGP advertise function, you need to install kube-ovn-speaker and annotate pods/subnets that need to be exposed.
 
+
+1. Label nodes that host the BGP speaker and act as overlay to underlay gateway
+```bash
+kubectl label nodes speaker-node-1 ovn.kubernetes.io/bgp=true
+kubectl label nodes speaker-node-2 ovn.kubernetes.io/bgp=true
+```

 ## Install kube-ovn-speaker
 
-1. Download `kube-ovn-speaker` yaml
+2. Download `kube-ovn-speaker` yaml
 
 ```bash
 wget https://github.com/kubeovn/kube-ovn/blob/master/yamls/speaker.yaml
 ```
 
-2. Modify the args in yaml
+3. Modify the args in yaml
 
 ```bash
 --neighbor-address=10.32.32.1  # The router address that need to establish bgp peers
 --neighbor-as=65030            # The AS of router
 --cluster-as=65000             # The AS of container network
 ```

+4. Apply the yaml
 
 ```bash
 kubectl apply -f speaker.yaml

-```bash
-kubectl label nodes speaker-node-1 ovn.kubernetes.io/bgp=true
-kubectl label nodes speaker-node-2 ovn.kubernetes.io/bgp=true
-```
 
 *NOTE*: When more than one node host speaker, the upstream router need to support multiple path routes to act ECMP.
