[j-nsp] Traffic monitoring per ASN

[Andrey A. Ryazanov]

If AS6848 is the only one you want get stats for, you may try SCU/DCU accounting feature.
It's possible to classify traffic by AS path, configure SCU/DCU and then run MRTG to 
fetch data from jnxScuStatsTable or jxDcuStatsTable SNMP tables to obtain counters per 
class.

Configuration is smth. like this:

# this is upstream interface (SCU input interface)
sg at br1> show configuration interfaces so-0/1/0 unit 0 family inet accounting          
source-class-usage {
    input;
}

# this is interface towards my network (SCU output interface and DCU interface)
sg at br1> show configuration interfaces ge-0/0/0 unit 705 family inet accounting    
source-class-usage {
    output;
}
destination-class-usage;

sg at br1> show configuration routing-options forwarding-table 
export route-coloring;

sg at br1> show configuration policy-options policy-statement route-coloring 
term AS6848 {
    from as-path AS6848-routes;
    then {
        forwarding-class AS6848;
        accept;
    }
}
then {
    forwarding-class other;
    accept;
}

sg at br1> show configuration policy-options as-path AS6848-routes 
".* 6848 .*";

Of course you may maintain as many classes as you need, but keep in mind there's a limit 
for its number (64 on my M20, as far as I remember).
