The filters application adds functionality for packet filtering.

A properly hardened communication network has traffic filters in place to protect the network from malicious or malfunctioning client devices.

Usually, a combination of hardware and software filters are used: hardware filters operate on the linecard, and are able to drop packets that match certain criteria, often at line rate. Software filters provide an additional layer of security for packets that are destined for the CPU (control plane traffic).

Use Filters for:

  • Dropping traffic from a certain IP subnet into a Router service
  • Rate-limiting packets with the broadcast MAC address ff:ff:ff:ff:ff:ff as destination

Use ControlPlaneFilters for:

  • Only allowing SSH / BGP connections from a particular IP-subnet
  • Rate-limiting the number of ICMP Echo requests processed by the node
