A policy is a mechanism in the JUNOS policy framework that allows you to configure criteria against which something can be compared and an action that is performed if the criteria are met.
All policies in the JUNOS policy framework share the following architecture and configuration fundamentals:
- Control Points
- Policy Components
- Default Policies and Actions
- Configuration Tasks
- Policy Configuration Recommendations
NOTE: This section highlights the fundamental architecture that all policies share. Note, however, that the implementation details of routing policies and firewall filters are very different. For information about these differences, see Comparison of Routing Policies and Firewall Filters.
