> Hello, @weizhouapache

> > Can you perform the tests ?
>
> Sure! Below are described some connectivity stress tests that I performed
in my local environment. They were executed over a VPC (CIDR 10.0.0.0/16), with
a tier (CIDR 10.0.0.0/24) whose ACL was configured to allow all ingress and
egress network traffic. I acquired a public IP (192.168.122.15) for the VPC and
assigned it to a VM provisioned in the tier. In the VM, I configured a UDP
server with Node.js and started it as a daemon:
>
> UDP Server
> ```js
> const udp = require('dgram')
> const fs = require('fs')
>
> const server = udp.createSocket('udp4')
> const port = 2222
>
> const logStream = fs.createWriteStream('udp.log', { flags: 'a' })
>
> server.on('error', (error) => {
> logStream.write('Error: ' + error)
> server.close()
> })
>
> server.on('message', (msg, info) => {
> const message = msg.toString()
> const logEntry = `[${new Date().toISOString()}]
${info.address}:${info.port} - ${message}\n`
> logStream.write(logEntry)
> console.log(logEntry.trim())
> })
>
> server.on('listening', () => {
> logStream.write('Server is listening at port ' + port)
> })
>
> server.on('close', () => {
> logStream.write('Socket is closed')
> logStream.end()
> })
>
> server.bind(port)
> ```
>
> Next, I developed a client script to send UDP datagrams to the server
every 100 milliseconds:
>
> UDP Client
> ```js
> const udp = require('dgram')
>
> const host = '192.168.122.15'
> const port = 2222
> const sleepInterval = 100
>
> const client = udp.createSocket('udp4')
>
> function randomIntFromInterval(min, max) {
> return Math.floor(Math.random() * (max - min + 1) + min)
> }
>
> let i = 0
> async function sendDataToServer() {
> const message = 'load test #' + (i++).toString() + ' -- data:' +
Date.now().toString(36).repeat(randomIntFromInterval(100, 150))
> console.log(message)
> const data = Buffer.from(message)
>
> client.send(data, port, host, (error) => {
> console.log('sending data to the server')
> if (error) {
> console.log('error - closing socket')
> client.close()
> }
> })
> }
>
> setInterval(sendDataToServer, sleepInterval)
> ```
>
> ## Non-redundant VPC cleanup
> ### Reusing the same MAC address
> 1. Using a non-redundant VPC, I started the server and ran the client
script to begin sending UDP datagrams to the server.
> 2. Cleaned up the VPC.
> 3. The UDP datagrams from `#396` to `#420` and `#422` to `#427` were
dropped and it took about 3 seconds for the connection between the client and
server to be reestablished.

> 1. I started the server and ran the client script to begin sending UDP

delay of about 3 seconds between datagrams `#102` and `#104`.

> We can observe that using a new MAC address for the public NIC of VRs will
not bring connectivity overhead. It is also important to highlight that this
enhancement aims to avoid the VR's operating system interpreting the network
traffic received during cleanups as spoofing attacks. It does not have the goal
of improving network connectivity or things like that.
thanks @bernardodemarco
looks good
can you grep "arping" in the /var/log/cloud.log in the backup VR (now it
should be primary VR) ?
can you test also port forwarding and load balancing rules, other than
static nat ?
thanks
