[Xorp-users] Simple multicast configuration

    I've been trying for a couple of days to configure a very simple multicast configuration:

WinXP Pro #1
160.254.1.10
     |
     |
     |
169.254.1.2
LiveCD 1.4
169.254.2.1
     |
     |
     |
160.254.2.20
WinXP Pro #2


    All 3 machines run as virtual machines in VMWare. The result is that unicast works perfectly fine, but no way for multicast, neither asmping nor VLC can reach from one to the other computer.
    I'm totally at loss, don't know what else to try, any help will be very appreciated. The xorp.cfg file is:
