[Freeswitch-users] rtp multicast paging

[Brian Snipes]

Any ideas on getting multicast to go out a vlan interface on Linux?  I
have a server with : 

eth0->192.168.1.2
Vlan : eth0.5-> 192.168.5.2 and 192.168.5.4

With bind_server set to 192.168.5.4, if I start a multicast page all of
the multicast paging packets go out from 192.168.1.2 - both the page
data and the control packets.  I do see control packets going out on
192.168.5.2 but not the page data.  Multicast was added using :

route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0.5

On eth0 I see (an excerpt):
17:08:08.608714 IP 192.168.1.2.27872 > 224.168.168.168.34567: UDP,
length 172
17:08:08.648713 IP 192.168.1.2.27872 > 224.168.168.168.34567: UDP,
length 172
17:08:08.648854 IP 192.168.1.2.27872 > 224.168.168.168.34567: UDP,
length 172
17:08:08.728581 IP 192.168.5.2.48372 > 224.168.168.168.6061: UDP, length
8
17:08:08.728586 IP 192.168.5.2.48372 > 224.168.168.168.6061: UDP, length
8

On eth0.5 I see:
17:08:38.878884 IP 192.168.5.2.48372 > 224.168.168.168.6061: UDP, length
16
17:08:38.878967 IP 192.168.5.2.48372 > 224.168.168.168.6061: UDP, length
16
17:08:43.840213 IP 192.168.5.2.48372 > 224.168.168.168.6061: UDP, length
8
17:08:43.840222 IP 192.168.5.2.48372 > 224.168.168.168.6061: UDP, length
8

Any ideas on the proper way to get the packets to flow out the eth0.5
for paging on Linux?
