Adding Multicast Routing to a Specific Network Interface
ip route add 224.0.0.0/4 dev <device-name>
More details about ip can be found here
The equivalent "route" command is:
route add 224.0.0.0 netmask 240.0.0.0 dev <device-name>
Routing Configuration that Survives Reboot
Add the static routing configuration to /etc/sysconfig/network-scripts/route-<device-name>:
... # default multicast route 224.0.0.0/4 via 172.20.1.12
where "172.20.1.12" is the IP address of the interface we want to route the multicast traffic over.
After reboot, we'll get this:
[eap@app01 ~]$ ip route ... 224.0.0.0/4 via 172.20.1.12 dev eth1
