Junos OS

Hello team:

I want to test my MVPN environment beyond sending a bunch of ICMP packets.

¿ Would you please point me to free client/server streaming tools for this purpose? If possible, with Apple Mac support. If possible, easy to install please 🐵

Thanks!

Hello,

VLC is the one to go for:

1/ VLC for MAC download link https://www.videolan.org/vlc/download-macosx.html

2/ how to make VLC stream multicast https://peakdrive.com/?p=440 

3/beware of default TTL==1! How to adjust mcast TTL in VLC https://forum.videolan.org/viewtopic.php?t=56351

Thx

Thank you Aarseniev! 

Best regards, Rogelio

Hi Ralvez 

There are different options to run multicast stream, the most popular option is VLC, having a client(PC) and server(PC) running VLC and stream a video, once you have it enabled, make sure you set TTL higher than 1 , otherwise it will be dropped in the first hop

Download VLC : https://www.videolan.org/vlc/

You can try this one, however i'm not very handy with MAC.

Last but not least, in Juniper(some platforms support it , some not, to know if its supported, try if that command can be auto-completed) you have the option to do SAP (Session Announcement Protocol ) , this is a quick method to test multicast, for example :

We have an MX router with SAP enabled in 225.1.2.3 , then in the other side of the network you want to run ping bypass to that address, here is a better view:

MX-1(SAP)---<---cloud-----> MX-2(ping bypass)

MX-1 : set protocols sap 225.1.2.3 5000 - https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/multicast-sap-config.html

MX-2: ping 225.1.2.3 bypass-routing ttl 30 interface <outgoing interface>

After that, you should be able to ping 225.1.2.3(it should respond to icmp), if multicast is enabled properly in your network.

Hope this help! 

Thank yoy Franky! I will give it a shot.
