I need to implement DVMRP protocol to route multicast over Openvpn (tun) connection for some old 3Com NBX phones.I use Debian squeeze so mrouted is not available (obsolete). What can I use instead? 
Alternative to mrouted for DVMRP on Debian Squeeze
networking;ip;routing;multicast
Ok, after some search I found this: http://freecode.com/projects/mroutedI downloaded the latest source code (2011) and it compiled flawlessly on 64-bit cpu.Thank you all anyway!
