I don't see any error here.  The warning abut multi-cast is just
a warning and should not affect the operation (unless you are trying
to use IPv6)

Since you've obviously trying to use the synthetic Linux target,
does your I/O adapter [the auxiliary program that runs on Linux and 
provides network access] know about both interfaces?

Have you made sure that you understand the process with a single
network interface?  The manual has a good explanation of how to
run programs on the synthetic target, how to set up the auxiliary,
etc.  Run some of the standard network test programs under this
scenario, then proceed to getting two networks running.
