Network and Security Testing Tools for SD-WAN, iBGP, and ADVPN.

Here is a repo for some useful tools to test SD-WAN implementations (tested on Ubuntu 18.04 and 20.04*):

• Ekiga Softphone for failover testing between Hubs and Branches.
• iperf3 for Load Balance testing.
• FIT for application steering testing.

1. Ekiga Softphone Quick Install Steps (*currently not supported on Ubuntu 20.04):

    sudo apt update
    sudo apt-get install ekiga -y

• Using RDP or console from ESXi or KVM, connect to both branch Ubuntu VMs, let's use branch1 and branch2 as an example.

• Launch the Ekiga Softphone on both and enter the IP of branch2 on branch1.

• Click the green phone icon to call and establish a session.

• Go to branch2 console and accept the call if the auto answer feature is not enabled.

• To download Ekiga for Windows, go here: https://www.ekiga.org/download-ekiga-binaries-or-source-code.

2. iperf3 Quick Install Steps:

    sudo apt update
    sudo apt-get install iperf3 -y

• In order to generate 4 simultaneous streams using iperf3 between two Ubuntu VMs

  • SSH into the Hub Ubuntu instance and issue:

    » iperf3 -s -p 6001 -i 1
    

  • From the the Branch Ubuntu instance SSH session issue:

    » iperf3 -c <ip address of Hub> -p 6001 -u -i 1 -t 1200 -b 1M -l 1360 -P 4
    

  • This should initiate 4 streams from the Branch to Hub, and from here you can run SLA load balance and failover testing.

  • More information can be found here on iperf3 command syntax: https://iperf.fr/iperf-doc.php.

• iperf3 can also run on Windows, to download go here: https://iperf.fr/en/iperf-download.php#windows
