The following terms and concepts may help as you read this section.
Effects of Zones on Different Types of Traffic
Zones effectively divide traffic into three types--intra-zone traffic, inter-zone traffic, and extra-zone
traffic--which are affected differently by zone-based security and policy settings.
Intra-zone Traffic
• Intra-zone traffic is traffic between interfaces in the same zone.
• In each zone, you can either allow or prohibit all intra-zone traffic.
• You can also set up firewall rules to control intra-zone traffic, but many other types of zone-based
security and policy settings do not affect intra-zone traffic.
Inter-zone Traffic
Inter-zone traffic is traffic between interfaces in different zones.
Extra-zone Traffic
• Extra-zone traffic is traffic to or from any interface that is not assigned to a zone.
Some zone-based security and policy settings may apply to extra-zone traffic, especially if you can
set the zone attribute in them to Any or All. See the specific feature for more information.
