All Palo Alto Networks customers with a support account can use the Palo Alto Networks WildFire portal to manually submit up to five samples a day for WildFire analysis. If you have a WildFire subscription, you can manually submit samples to the portal as part of your 1000 sample uploads daily limit; however, keep in mind that the 1000 sample daily limit also includes WildFire API submissions.

Support for multiple instances per link - With OSPFv3, you can run multiple instances of the OSPF protocol over a single link. This is accomplished by assigning an OSPFv3 instance ID number. An interface that is assigned to an instance ID drops packets that contain a different ID.

The interface ethernet1/15 is configured as a layer 3 interface. Subinterfaces corresponding to each one of the VLAN are created off of the parent interface Ethernet 1/15. Each subinterface is assigned a VLAN tag and an IP address corresponding to the VLAN provides connectivity.

Note: Inter VLAN routing with each VLAN in a unique IP subnet In order for network devices in different VLANs to communicate, a router must be used to route traffic between the VLANs. While VLANs help to control local traffic, if a device in one VLAN needs to communicate with a device in another VLAN, one or more routers must be used for inter VLAN communication. In this configuration a Palo Alto networks firewall can used to securely route traffic within the VLAN. This is also commonly called "one arm routing" or "router on a stick".
