Policy Options -> Firewall Filters
irewall Filter Policies control traffic at the interface level. Firewall filters let you filter packets based
on their components and act on packets that match the filter.
These filters can restrict the local packets that pass from the router’s physical interfaces to the
Routing Engine. Input filters affect only inbound traffic destined for the Routing Engine, and
output filters affect only outbound traffic sent from the Routing Engine. Policing, or rate limiting
provides a finer level of control over local packets destined for the Routing Engine. (See Policy
Options -> Policers on page 467.)
For each interface, you can apply a firewall filter to incoming or outgoing traffic, or both, and can
use the same filter for both. Type of traffic supported includes IPv4 and MPLS.
