[j-nsp] Prefix-Specific Actions internals ?

[Laurent Gyde]

Hi,

A question about Prefix-Specific Actions, we'd like to limit traffic on 
a per subnet (/24) basis, without having to explicitly specify each 
subnet range. The idea is to tell the following to Junos:
***********************
prefix-action psa-per-subnet {
    count;
    destination-prefix-length 24;
    policer subnet-policer;
    subnet-prefix-length 0;
}
***********************
This is reasonable only if our box generate each subnet context as the 
traffic to this subnet is forwarded (in our case we would get about 3000 
contexts) but not if all the contexts are build whether there is some 
traffic or not  (wich would give 2^24 contexts !).

Does someone know more about this question ?

    Thank's,

        Laurent Gydé
