Question on botroutes

[NyghtWalker]

Currently I'am working on adding botroutes to a rather simple map of mine. I have a catwalk in one area with the botroutes covered rather well below it. Question is how do I make the bots jump up onto the catwalk and continue on from there? There are no stairs or what not for them to climb so jumping is really the only option, and not having them go up there would give too much of a "rest break" spot to players.
