Prefixes

Learn how to configure prefixes to set path set policies and priorities.
A prefix is a group of one or more individual IP addresses or IP address subnets. Prefixes are used with Path Set Policies and Priority Policies. They can be either global or local in scope.
  • Global prefixes are used when traffic of interest across all sites in a network can be identified with the same set of prefixes. For example, facilities infrastructure or print services for an enterprise.
  • Local prefixes are used when specific prefix values change by branch location. Use of local prefixes can simplify creation and administration of rules. For example, a subset of IP addresses within a subnet.
    Prefixes configured under path are only applicable for Path Policy Sets and prefixes configured under QoS are only applicable for QoS Policy Sets.
