Monitoring Traffic on a Router with a VRF Instance and a Monitoring Group

The first way you can implement passive flow monitoring is to direct traffic into a VRF routing instance and use a monitoring group to export this traffic to a flow server for analysis. Complete the following tasks:

• Specifying a Firewall Filter on an M, MX or T Series Router to Select Traffic to Monitor

• Configuring Input Interfaces, Monitoring Services Interfaces and Export Interfaces on M, MX or T Series Routers

• Establishing a VRF Instance on an M, MX or T Series Router for Monitored Traffic

• Configuring a Monitoring Group on an M, MX or T Series Router to Send Traffic to the Flow Server

• Configuring Policy Options on M, MX or T Series Routers

• Stripping MPLS Labels on ATM, Ethernet-Based and SONET/SDH Router Interfaces
