[Xorp-users] XORP IGMP Querier

[Yuri Kirsanov]

Good day.
I'm trying to use XORP as IGMP Querier to provide IpTV in our network. I use 
PIM-SM4 and IGMP, everything works just fine, but XORP doesn't act as an IGMP 
Querier. I mean it just doesn't send any group-specific IGMP queries 
periodically. It does send group-specifict IGMP message when user leaves a 
group to ensure there's nobody else left in group. Can anybody help me on this 
issue? I am sure that XORP is IGMP querier on that vif:

root at video_gw> show igmp interface
Interface    State    Querier         Timeout Version Groups
eth0         UP       172.17.17.8        None       2     10
eth1.202     UP       192.168.202.1       246       2      3

By the way, what does "Timeout None" mean?

Here's my IGMP groups:
root at video_gw> show igmp group
Interface    Group           Source          LastReported Timeout V State
eth0         224.0.0.2       0.0.0.0         172.17.200.47      80 2     E

Group 233.163.114.173 is my source of multicast traffic, TV channel actually. 
It's Timeout value goes to zero and then group disappears.
