Only one program at the same time can set the MRT-Flag to use the multicast routing tables. To set the flag you need root privileges. To change the flag manual you can overwrite the following file:18 MRT-Flag:: If the multicast routing flag is set, then the Linux-Kernel is initialize to forward multicast traffic. Only one program at the same time can set the MRT-Flag to use the multicast routing tables. Notice for both IP version exist a MRT-Flag, so you can run IPv4 and IPv6 multicast forwarding programms at the same time. To set the flag you need root privileges. To change the flag manual you can overwrite the following file: 19 19 {{{ 20 20 /proc/sys/net/ipv<X>/conf/default/mc_forwarding … … 45 45 [[Image(szenarios1b.png, 140px, right)]] 46 46 47 This is the easiest scenario.

In this example we used a tunnel interface as second downstream. This is legitimate but you must ensure that the tunnel support multicast. An normal ip2ip tunnel doesn't support this (use a [http://www.linuxdoc.org/HOWTO/Adv-Routing-HOWTO/lartc.tunnel.gre.html gre] or a tap tunnel). 99 Because you cannot run the mcproxy more than one time with the same IP version (see MRT-Flag). 100 101 In this example we used a tunnel interface as second downstream.
