Hi,

  We have a doubt when we recieve an MRPI alert "SG Creation Alert" . In nut
shell this alert is sent to all routing protocols when an multicast packet
doesn't have the S,G entry in the forwarding cache.
  Well our doubts are, 
 
 1. In GateD source code, they process the SG creation alert for an source
which is remote, we don't know what is meant by remote source. Can somebody
suggest some topology for getting this alert for a remote source.

2. . Should all the igmp hosts are directly connected to the DR of the LAN .
3.. Should DR  necessarily be the querier of the LAN ??.

Expecting your valuable replies,
Thanks
Arvind
