Thanks for your reply, but the route itself is not the problem as far as
I know.
When I tried your approach, it didn't quite work, maybe you have a
different (or newer/older system) than mine? (FC6 here).
However after some searching around on my system I found a sysconfig
file that described all the files that sysconfig accepts inside its
directory. One of them was a file called "route-[interface]". When I
created that file, the route did get added upon ifup'ing the interface.
However, without "allmulti" it still didn't work.
Some output (the X's is my own external route/gateway to the Internet) :
