How to enable MPLS Accouting with Netflow Feature?

如果要讓Netflow支援MPLS這種比較進階的traffic flow,就必須使用version 9。
建議各位可以參考以下幾份文章:

MPLS Egress NetFlow Accounting

MPLS-aware NetFlow

Configuring MPLS-aware NetFlow

假設現在題目要求在Serial 0/0介面上進行MPLS Label Accounting,同時要將資料輸出到100.1.1.1 Port 1001這台Netflow Server:

interface Serial0/0
ip route-cache flow
mpls netflow egress
!
ip flow-export version 9
ip flow-export destination 100.1.1.1 1001
ip flow-cache mpls label-positions
