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.
