Hello all!

We have two fedora routers one at each site. What we are trying to do worked using freesco but not on fedora, i'm not very good at scripting and need a little guidence. Basicly what we are trying to do is if the primary line dies, the router will change it's routes to go through our t1 line. Here's the script and i'm getting an error saying "syntax error near unexpected token `{ `initial_routes() {"

We had this working on two freesco boxes, but those became a little unstable. We were having issues with freesco seeing or detecting nics and keeping the virtual nic. If anyone can post a link or anything it would be greatly appreciated.
