If you type netstat -rn you'll find that you have a route for E.F.G/ 
28 via fxp0 already. If you want to add other routes then use the  
"route(8)" command. e.g to route traffic for the rest of E.F.G/24 via  
E.F.G.254  " route add -net E.F.G/24 E.F.G.254" would do. To make  
such extra routes persistent then add something like ...

static_routes="efg"
route_efg="-net E.F.G/24 E.F.G.254"

to your rc.conf. Read the rc.conf and route(8) man pages for more  
info on that.
