[j-nsp] Track-IP functionality in Junos

Masood:

Therea re two ways you can do this:

(a) BFD liveness:

(b) Generate a periodic event that triggers an event policy that does the ping and removes the static route if the ping fails:

For "B" look at page 367 on how to generate an internal event based on a timer.  You can name the event whatever you want.  When the timer goes off, an "event" is generated internally with that name, that will trigger a corresponding eventscript that will do the work you need.  

At least... if its ping you want... I think "B" will work.  I think I'm going to go lab that up actually, I haven't done this before... but it makes sense, it should totally work.
