Security Features and VPN Support of the ISR4321-AXV/K9
The ISR4321-AXV/K9 Cisco 4000 Series 2 Ports 4 Slots Gigabit Ethernet Router is equipped with several security features to protect your network and data:
- Firewall: The router has a built-in firewall that can be configured to block unauthorized access and protect against external threats.
- VPN: The router supports VPN (Virtual Private Network) connections, which allows remote users to securely access the network over the internet.
- Intrusion Prevention: The router has an integrated intrusion prevention system (IPS) that can detect and prevent malicious attacks on the network.
- Authentication: The router supports various authentication methods, such as RADIUS, TACACS+, and local authentication, to ensure that only authorized users can access the network.
- Encryption: The router supports data encryption to protect sensitive information from being intercepted and read by unauthorized parties.
- Quality of Service (QoS): The router has QoS capabilities that allow you to prioritize different types of traffic, ensuring that critical applications receive sufficient bandwidth.
- Network segmentation: The router supports VLANs (Virtual Local Area Networks) that allow you to segment your network into smaller, more secure subnets.
Multiprotocol Label Switching (MPLS) Support
The ISR4321-AXV/K9 Cisco 4000 Series router supports Multiprotocol Label Switching (MPLS) through its built-in routing protocols and features. MPLS is a mechanism used to forward packets in a network based on labels instead of traditional routing tables. This allows for faster and more efficient routing of packets, as well as the ability to create virtual private networks (VPNs) and other advanced networking features.
The ISR4321-AXV/K9 has two Gigabit Ethernet ports and four expansion slots, which provide the necessary connectivity and expandability to support MPLS. The router also has a powerful processor and memory, which allow it to handle large amounts of traffic and provide fast routing performance.
Virtual Routing and Forwarding (VRF) Support
The ISR4321-AXV/K9 Cisco 4000 Series 2 Ports 4 Slots Gigabit Ethernet Router supports Virtual Routing and Forwarding (VRF). VRF is a technology that allows multiple routing tables to exist within the same router. This allows for the creation of separate virtual networks within the same physical network, providing increased security and isolation between different groups of users or devices. The ISR4321-AXV/K9 supports up to 10 VRFs, each with their own routing table and interfaces. This allows for the creation of multiple virtual networks within the same physical network, providing increased security and isolation between different groups of users or devices.

About Refurbished Products
Routers lead the line as the first line of network security in homes and offices. It prevents intrusion into a network while creating a firewall to provide the highest level of security on several network types. They are the best ways of keeping computer systems, network systems, and information contained in them safe from intrusion.
A router is designed to be more capable than several other network devices such as hubs or switches that can only carry out basic network functions. For instance, a hub only transfers data between network devices without analyzing or doing anything with those data. On the other hand, routers are able to analyze data sent between network devices. They can change the packaging of such data and send it over to a different network.
Routers are the perfect devices to share an internet connection between multiple computers in home networks. A router typically connects to the modem using a network cable. Router networking occurs via a WAN port or the internet. There are also wireless routers that connect to devices using different wireless standards.
The hardware inside these routers allows them to cope with several network use at the same time. Many of these routers come with dual-core and quad-core processors. These processor options allow them to handle lots of data more effectively. Users can use their Wi-Fi routers for activities such as video streaming, online gaming, data backups, and more. Even while carrying out those operations, the routers perform at the highest levels.
Users will get routers that broadcast wireless signals over two frequencies (for dual-band) or more (for tri-band and others). These routers run at frequencies that can cover a wide expanse of area. They are not congested and are perfect for office buildings, homes, and large enterprises. Clients will find routers that emit their signals between 2.4 GHz and 5GHz.
Built-in Security Features
These router networking devices also come with security features such as device quarantine, firmware updates, automatic updates, and more. The features allow them to provide network-level protection against attacks. With these features, cybercriminals will be unable to infiltrate home networks.
Types of Routers
There are several types of routers that users can benefit from. Some of them include:
- Core Routers. These are the types used by Internet Service Providers. They are the fastest and most powerful types. They sit at the center of the internet and forward data through the main fiber Optics.
- Wireless Routers. These work in a similar manner as a home or business LAN. However, they give room for better mobility for laptops, tablets, and other portable devices. These types offer transmission over short distances.
- Enterprise Routers. These are the types employed by large companies. Organizations use enterprise routers to connect their networks to these core routers.
- Branch Routers. These types connect an enterprise's remote offices to its Wide Area Network (WAN). They come with improved features such as wireless LAN management, time-division multiplexing, WAN acceleration, and more.
- Edge Routers. These are the most commonly used types in homes and small businesses. They are low-capacity devices that connect to the public internet or private WAN, or external LAN.
- Logical Routers. They function similarly to hardware to create several network routes.
