<div>I think the <a href="http://224.0.0.0/24" target="_blank">224.0.0.0/24</a> subnet is reserved for routing protocols. Try changing to another subnet and see if that works better.</div>

<b>Ämne:</b> [Xorp-users] Multicast Forwarding Problem<br>
</font><br>
</div>
<div></div>
<div>
<div>Hi,</div>
<div><br>
</div>
<div>I am new to XORP and am trying to get multicast forwarding to work in a CORE emulation environment. The network I’m working with is one simulated router connected to three hosts, each on a separate subnet. My goal is to distribute multicast traffic from
one transmitter to two receivers. The multicast ip I’m using is 224.0.0.3. My config file for the router is below. Also, I’m using Quagga for OSPF which seems to be working fine.</div>
<div><br>
</div>
<div>Using tcpdump, I can see the traffic coming into the router interface but it just dies there. For some reason the IGMP joins are not being registered even though the IGMP reports are being sent to the router. The router also never issues a query on 224.0.0.3
but does on other IP’s.</div>
<div><br>
</div>
<div>Any help would be most appreciated, I’ve been chasing this for three days now and am running out of things to try.</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>
</div>
