[j-nsp] Data Plane Memory in JUNOS 10.3R1.9

[Lawrence Wong]

Thanks Rob.

How about for the "IDP data plane memory"? Is it preallocated as well?

Seems like a big waste if the box is running in packet mode and/or IDP is not 
enabled.

Is the 204 MB of memory really used/reserved or is it more of a placeholder on 
the max available to be used?

Regards,

All of the memory is preallocated and as of today its default usage can
not be decreased.
