Hi, I'm newbie

I tested pimd-2.3.0 on debian wheezy.

Kernel : 4.1.8

CONFIG_IP_PIMSM_V1=y
CONFIG_IP_PIMSM_V2=y
CONFIG_IPV6_PIMSM_V2=y
CONFIG_IP_MULTICAST=y
CONFIG_IP_MROUTE_MULTIPLE_TABLES=y

Sysctl Config

net.ipv4.conf.all.forwarding = 1
net.ipv4.conf.all.mc_forwarding = 1

net.ipv4.conf.all.force_igmp_version = 3

troglobit commented 9 years ago

Little bit difficult to understand what your problem is, the two routers seem to have peered properly and even established the multicast routes? Have you checked the TTL of the multicast (234.234.234.234) you are trying to route? Usually multicast defaults to TTL=1 ... and it needs to be greater than that for a router to be allowed to forward the stream.

fatihusta commented 9 years ago

Thanks @troglobit I tried command line vlc player and i set ttl. it's work.

minimum ttl 5 for my topology

commands

Sender (w2k12)

vlc.exe -vvv video1.mp4 :sout=#udp{dst=234.234.234.234:1234} :sout-keep --ttl 5

Client (win7)

vlc.exe -vvv udp://@234.234.234.234:1234
