[Xorp-users] multicast routing not working

[Dr Ben G Wu]

Hello,
I just found xorp 2 days ago and try to setup a multicast network. The
source is at 192.168.1.0/24 subnet and the multicast subscribers are
in 192.168.2.0/24 subnet. Centos 5 is running xorp with 2 physical
interfaces connecting the 2 subnets.

xorp is installed and xorp_rtrmgr running fine. The src is playing a
stream on 244.0.0.1:1234 using vcl player.  but the client could not
connect to 244.0.0.1.  the command " show mfea dataflow" returns
nothing.

My configuration file is as below.

     restore-original-config-on-shutdown: false
