I need to route a multicast streams in my private network.
I'm using pimd for multicast routing.
The multicast routing did not work until I put altnet <multicast_source_ip> masklen 24 to the pimd.conf file.
The problem that I do not always know what the <multicast_source_ip>.
I still not understand what the altnet directive is doing? According to the pimd.conf file:
# If you want to add "alternative (sub)net" to a physical interface,
# e.g., if you want to make incoming traffic with a non-local source address
# to appear as it is coming from a local subnet, then use the command:
# phyint <local-addr | ifname> altnet <net-addr> masklen <len>
# XXX: if you use this command, make sure you know what you are doing!!
And how can I solve this problem without <multicast_source_ip> using?
