Hi All,
I have two PCs with Red Hat Linux installed in them. Both have two NICs.
XORP-1.4 is running in PC-A with IGMPv3 and PIM-SM enabled. PC-A and
PC-B are connected to each other through both interfaces.
PC-A eth0: 10.100.3.107/24
PC-A eth1: 192.168.14.212/24
PC-B eth1: 10.100.3.220/24
PC-B eth0: 192.168.14.211/24
PC-A eth0 and PC-B eth1 are directly connected to each other. Similarly,
PC-A eth1 and PC-B eth0 are directly connected to each other.
Here, 192.168.14.211 is configured as static RP in PC-A. I am
sending IGMP join report for 232.11.22.33 group and 192.168.14.14 source
with INCLUDE mode from 10.100.3.220. I have sent PIM hello message from
192.168.14.211. As IGMPv3 and PIM-SM are runing on PC-A, it should
convert that report into PIM JOIN(S,G) message and send it towards
RP(192.168.14.211). But no message was sent by PC-A on its eth1. Tell me
where I went wrong?
I have copied my configuration file and condition of PC-A when I
sent the IGMP report.

*I have made 192.168.14.211 as static RP from configuration mode of xorpsh.
Here is the command: set protocols pimsm4 static-rps rp 192.168.14.211
