Hi every master:
I have some question about mrouted, my mrouted can't work, always had error message as below :
[root@(none) mrouted]# mrouted -c /etc/mrouted.conf -d
debug level 2
11:17:19.541 mrouted version 3.8
11:17:19.862 Can't enable Multicast routing in kernel: protocol not available

I had configure as below:
IP:multicasting routing
IP:IP tunneling
route add -net netmask dev eth0

Am i forget to site anything?
How do I enable multicast routing?
Every master help me please, thank you.
