Applying a Firewall Filter Output Interface on an M, MX or T Series Router to Port-mirror Traffic to PICs or Flow Collection Services
On output interfaces, you can apply a firewall
filter that leads to a filter-based forwarding routing instance. This
is useful if you want to port-mirror traffic to multiple Monitoring
Services PICs or flow collection services interfaces. To configure,
include the output statement at the [edit interfaces interface-name unit logical-unit-number family inet filter] hierarchy level.
