Just a quick note here,
you may also opt to use "distribute-list with route-map" at R3,
to filter inbound routes based on next-hop value (or output interface),
directly at "receiving" router.
filtering with distance won't work here, since external routes all have the
same
advertising RID (route-source).
Everything else should probably use "database-filter" or cost manipulation
in some
way (max-metric falls under that category too), to adjust forward-metric.
