[j-nsp] Track-IP functionality in Junos

[Erdem Sener]

Hello,

 Current JUNOS versions only support CLI commands to be triggered via
op/event scripts. This means that you can't
currently trigger a configuration change (delete route, deactivate
neighbor, change localpref etc) based on those.

Altering of the configuration via op/event scripts will be supported
in 9.3 onwards.

HTH,
Erdem
