'Routing configuration to forward multicast traffic to a single NIC on RedHat 6

I'm trying to edit /etc/sysconfig/network-scripts/route-eth0 to make all multicast packets sent to device eth0 on RedHat 6.3, following this guide.

I tried writing like:

224.0.0.0/4 dev eth0

but it never works.... How can I specify multicast routing on this file?

Solution 1:[1]

I think you should add route in /etc/sysconfig/static-routes

One more alternative solution to save permanent route is add your route command in following file.

/etc/rc.local
  • More option to look.

also Enable MC routing in kernel 

sysctl -w net.ipv4.conf.all.mc_forwarding=0

Make sure you have MC routing support in kernel. for example. 

# cat /boot/config-`uname -r` | grep IP_MROUTE
CONFIG_IP_MROUTE=y

Netstat also tell you whether it enable or not

netstat -g
