I can only second this.  If you have a dedicated point-to-point interface for 
things, tacking the route on the interface is usually more robust than
pointing towards a gateway IP that might not be there, or might be learned
recursively over another interface, etc.

For multiaccess-links, *don't* do "ip route 0.0.0.0 0.0.0.0 eth0", of
course (use "... eth0 <gateway_ip>").  Just to make this very clear.

One can tack a *name* to routes?  Need to test this :-)

Does this name get carried in IGPs?  Or is it just there in the config
to document things?
