Dmitry,
You are effectively doing transparent bridging. From the
transparent bridge domain, the source-routed domain appears to be a
transparent bridge domain. I do not believe there is ever a case where
an application running IP will try to source route its traffic;
therefore, the source-route config doesn't do anything. It is
*possible*, but it doesn't make any sense to use it.
