1. Juniper SRX Series Devices and Features

Juniper SRX series and security features are the topics which will be discussed in this section.
Juniper SRX devices are classified based on the location that will be used, like LAN, data center, branch offices and virtual environment.
Juniper SRX is primarily a firewall and therefore supports the features that are supported in firewall in any other vendor like traffic filtering, NAT, VPN and some new or next-generation features like user based filtering, application firewall and UTM features like antivirus and antispam.

23. Juniper Firewall Filter Configuration Example

Juniper firewall filter is a Junos security solution to filter or control traffic at the data plane as they enter or exit an interface. It is exactly the same as access control list in Cisco devices.
The firewall filter is stateless, so it differs from the stateful Juniper security policy which is stateful. In other words, in firewall filter each packet must be inspected individually to determine whether it is permitted to be transmitted or it must be filtered.

20. Juniper Routing Instance Configuration

Juniper Routing Instance has the same concept of VRF in Cisco routers, which allows us to use a single physical router as multiple logical routers.
All logical routers in control plane and data plane are completely separate, so it can be assumed that there are actually multiple physical routers. The only difference is that the management plane is shared between routing instances (logical routers).
