Hi Guys,We have a HPE 5900 as a core-switch.
On this core we have a "vlan 113" for multicasting (IPTV)
On this vlan we have enabled igmp-snooping and igmp-snooping querier.
#
igmp-snooping
#
vlan 113
description IPTV
igmp-snooping enable
igmp-snooping querier
watching iptv IN the vlan works perfect.
At the same site we have vlan2. now we also want to wacht IPTV from vlan 2.
So we have to use multicast routing, sparse or dense mode.
The multicast routing fails in DM or SM.
if we configure Dense mode the streaming also stops in iptv vlan 113
CONFIGURATION DM
#
igmp-snooping
#
multicast routing
#

#
vlan 113
description IPTV
igmp-snooping enable

ip address 192.168.254.1 255.255.252.0
pim dm
igmp enable
#
interface Vlan-interface113
description IPTV

igmp enable
CONFIGURATION SM
igmp-snooping

c-rp 172.16.0.1
#
vlan 113
description IPTV
igmp-snooping enable
igmp-snooping querier
#
interface Vlan-interface2
description Data
ip address 192.168.254.1 255.255.252.0
pim sm
igmp enable
#
interface Vlan-interface113
description IPTV
ip address 172.16.0.1 255.255.252.0
pim sm
igmp enable
somebody knows whats wrong?
We have a Triax headend in iptv vlan 113 that generate the streams.
The strange thing is that if we start our own stream with vlc player and dm is configured, it works only with the vlc stream.
wireshark:
vlc packets: UDP stream --> TTL=5
triax head end: MPEG-TS stream (udp) --> TTL=16
THANKS!!!!!
Solved! Go to Solution.

Re: Comware Sparse/dense mode
I think you need to issue the pim-snooping enable command, per vlan.
display pim-snooping statistics and display pim-snooping routing-table could be useful for you here.
