There's nothing special that needs to be done, no patching, no special 
compile-time options, anything - you can just run XORP unmodified on 
top of IMUNES right now.  At the moment the functionality is limited to 
IPv4 unicast routing, though, with IPv4 multicast in the works.

>From the IMUNES downloads page (http://tel.fer.hr/imunes/dl) you can 
grab a bootable CD that also includes preinstalled XORP binaries.  The 
only problem is that due to a small bug (a missing soft-link) XORP 
routers on this bootable CD won't be started automatically, but if you 
check the web page tommorrow you'll probobaly find a corrected version.  
However, even with the current "buggy" CD you can start XORP manually 
by executing the following commands from the context of a targeted 
virtual node (router):

ln -s /tmp/@/Xorp.conf /tmp/Xorp.conf
/usr/local/xorp/bin/xorp_rtrmgr -b /tmp/Xorp.conf

You should also create group "xorp" before starting the rtrmgr (this 
will also be fixed on the next CD snapshot).

Hope this helps,
