<!-- Converted from text/rtf format -->
<P><FONT SIZE=2 FACE="Arial">Need some help enabling Multicast forwarding with XORP on a server running RHEL 5.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">We followed all the configuration items on the web and the users manual.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">We enabled each interface, fea, mfea, igmp and even pim in the XORP configuration with our specific information with no luck.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">This should be simple but for some reason MC Forwarding is not working. </FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Its a simple network with two hosts on either side of a server running XORP. </FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Here is our simple configuration:</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">mcast source---------------LinuxXORP-------mcast receiver</FONT>
<BR><FONT SIZE=2 FACE="Arial"> ^ ^ ^ ^</FONT>
<BR><FONT SIZE=2 FACE="Arial"> | | | |</FONT>
<BR><FONT SIZE=2 FACE="Arial"> 10.100.1.2 eth0 eth1 192.168.10.33</FONT>
<BR><FONT SIZE=2 FACE="Arial"> 10.100.1.3 192.168.10.34</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">We checked the output of the show igmp group command and can verify that eth1 is part of the group 225.1.1.2 that we are using. When we check the show route table ipv4 multicast final table we cannot see the multicast route being added.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Is there any configuration needed to static routing in the config.boot file?</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">We also verify that the source is sending on eth0 to 225.1.1.2 but its not being forwarded from eth0 to eth1.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Any help would be appreciated.</FONT>
