+Install a static source-specific route.  These routes are currently supported
+on Linux operating systems only, and perform AND matching on packet's
+destination and source addresses in the kernel's forwarding path.  Note that
+destination longest-prefix match is "more important" than source LPM, e.g.
+@command{"2001:db8:1::/64 from 2001:db8::/48"} will win over
+@command{"2001:db8::/48 from 2001:db8:1::/64"} if both match.
