FAQs

Why choose Juniper over Cisco? ›

Juniper excels in simplicity, high-performance routing, and strong security features. Cisco offers versatility, reliability, and a diverse product range, making it a better fit for organizations seeking comprehensive networking solutions with extensive industry support.

Upgrading or downgrading Junos OS can take several hours, depending on the size and configuration of the network.

The PFE uses special hardware, including ASIC chips, to efficiently forward traffic. PFE's do not use the CPU. In the vast majority of cases, the PFE can handle transit traffic without needing to involve the RE. This emphasizes the split between the control and data planes.

Power on the device and wait for it to boot. The software boots automatically. When the boot process is complete, you'll see the login: prompt on the console. Log in as the user root .

Ultimately, it comes down to your specific needs when deciding between Juniper Networks vs Cisco. While Cisco may provide a better price point with more features, Juniper may have higher performance products that are tailored to fit the exact specifications of business requirements.

The Bottom Line

Earning JNCIA-Junos certification is worth it because it is relatively straightforward to study for and opens up many possibilities for career advancement. If you fit into any of the outlined scenarios above, then this is the certification for you.

Just like any other operating system, the 64-bit version of the Junos operating system can address more memory than the 32-bit version of the operating system. To support larger Routing Engine memory sizes, an upgrade from the 32-bit to the 64-bit Junos OS, which is running on the Routing Engine hardware, is necessary.

As an alternative to entering CLI commands, Junos OS supports the J-Web GUI. The J-Web user interface enables you to monitor, configure, troubleshoot, and manage the router on a client by means of a Web browser with Hypertext Transfer Protocol (HTTP) or HTTP over Secure Sockets Layer (HTTPS) enabled.

Junos (and other vendors too) separate the control and data planes for performance and security. The PFE is specially designed to forward transit packet as fast as possible; The RE would only slow it down. The RE, on the other hand, can get overwhelmed if it gets too much exception traffic.

What is the difference between PFE and re? ›

Packets are routed and forwarded by the packet-forwarding engine (PFE), which is where all the specialized ASICs are located. The RE controls the router, handles the routing protocols, and performs all of the other tasks that can be handled more leisurely than wire-speed packet transit traffic.

Juniper Networks, Inc. is an American multinational corporation headquartered in Sunnyvale, California. The company develops and markets networking products, including routers, switches, network management software, network security products, and software-defined networking technology.

The console port allows access to a device running Junos OS, regardless of the state of the device, unless it is completely powered off. By connecting to the console port, you can access the root level of the device without using the network to which the device might not be connected.
