Prefixes

A prefix is an IPv4 or IPv6 network and mask expressed in CIDR notation (e.g. 192.0.2.0/24). A prefix entails only the "network portion" of an IP address: All bits in the address not covered by the mask must be zero. (In other words, a prefix cannot be a specific IP address.) Prefixes are automatically organized by their parent aggregate and assigned VRF.

Fields

Prefix

The IPv4 or IPv6 network this prefix represents.

Status

The prefix's operational status. Note that the status of a prefix does not have any impact on its member IP addresses, which may have their statuses defined independently. The "container" status indicates that the prefix exists merely as a container for organizing child prefixes.

Tip

Additional statuses may be defined by setting Prefix.status under the FIELD_CHOICES configuration parameter.

VRF

The Virtual Routing and Forwarding instance in which this prefix exists.

Note

VRF assignment is optional. Prefixes with no VRF assigned are considered to exist in the "global" table.

Role

The user-defined functional role assigned to the prefix.

Is a Pool

Designates whether the prefix should be treated as a pool. If selected, the first and last IP addresses within the prefix (normally reserved as the network and broadcast addresses, respectively) will be considered usable. This option is ideal for documenting NAT pools.

Mark Utilized

If selected, this prefix will report 100% utilization regardless of how many child objects have been defined within it.

Site

The site to which this prefix is assigned (optional).

VLAN

The VLAN to which this prefix is assigned (optional). This mapping is helpful for associating IP space with layer two domains. A VLAN may have multiple prefixes assigned to it.
