Example: Grouping Source Prefixes
Configure a routing policy to group source prefixes, and allow prefixes that match the policy statement to have a source class created for them.
[edit]policy-options {policy-statement set-gold-class {term {fromroute-filter 10.210.0.0/16 orlonger;route-filter 10.215.0.0/16 orlonger;then {source-class gold-class;}}}}
Apply a routing policy to the forwarding table with the corresponding source class.
[edit]routing-options {forwarding-table {export set-gold-class;}}
Enable packet counting on an interface. In this example, one interface accommodates both input and output.
[edit interfaces]interfaces ge/0/0/0 {unit 0 {family inet {accounting {source-class-usage {input;output;}}}}}
