Could not join Multicast group : No such Device

I would like to stream camera data over UDP multicast using gstreamer.

For that i used below pipeline,

gst-launch-1.0 v4l2src ! videoconvert ! video/x-raw,width=720,height=576,framerate=25/1 ! x264enc ! mpegtsmux ! rtpmp2tpay ! udpsink host=224.1.1.1 port=9090 auto-multicast=true sync=true async=false qos=true

But, I am getting below error,

could not get/set settings from/on resource : gstmultiudpsink.c(948): gst_multiudpsink_configure_client (): 
Could not join Multicast group : No such Device

But, the same pipeline is working in Ubuntu14.10 64 bit PC.

It didn't work on RHEL7 64 bit PC.

These both pc's are connected to same switch.

What is the problem here? and how can i solve this problem?

This answer helped me with a similar problem.

I configured a route for a multicast traffic with command

route add -net 224.0.0.0 netmask 224.0.0.0 enp0s3

where enp0s3 is my network interface's name.
