In Juniper Networks’ routers and switches, routing policies and firewall filters are two important concepts used to control the flow of network traffic.
Routing policies are used to determine how network traffic is forwarded or discarded by the router or switch. They are used to implement routing decisions based on a variety of factors, including source and destination IP addresses, protocols, port numbers, and other characteristics of the traffic. Routing policies can be used to prioritize traffic, implement Quality of Service (QoS) policies, control access to network resources, and implement security measures.
Firewall filters, on the other hand, are used to control access to network resources based on a set of rules defined by the network administrator. Firewall filters are used to filter traffic based on source and destination IP addresses, protocols, port numbers, and other characteristics of the traffic. They are used to enforce security policies, prevent unauthorized access to network resources, and protect against network-based attacks.
In essence, routing policies are used to control how traffic flows through the network, while firewall filters are used to control access to network resources. Together, these two concepts provide a powerful toolset for network administrators to manage and secure their networks.
