Support for Multiple WAN Connections

The Cisco 3925 SRE Bundle Integrated Services Router (C3925-VSEC-SRE/K9) supports multiple WAN connections, which allows organizations to establish redundant and diverse WAN connections to ensure high availability and reliability.

One of the key features of the C3925-VSEC-SRE/K9 is its support for multiple WAN interfaces, including Ethernet, T1/E1, and serial. This allows organizations to connect to multiple service providers, such as broadband, DSL, or cellular providers, and to establish diverse and redundant connections to ensure high availability and reliability.

The C3925-VSEC-SRE/K9 also supports load balancing, which allows organizations to distribute traffic across multiple WAN connections. This ensures that the router is able to use all available bandwidth, and to minimize the impact of a single WAN link failure.

Additionally, the C3925-VSEC-SRE/K9 supports advanced routing protocols, such as OSPF and BGP, which allow organizations to establish redundant and diverse WAN connections to ensure high availability and reliability.

High-Availability and Redundancy Features

The Cisco 3925 SRE Bundle Integrated Services Router (C3925-VSEC-SRE/K9) is designed to provide high availability and redundancy features to ensure that networks are always available and running smoothly. These features include:

  • Hot Standby Router Protocol (HSRP): HSRP allows multiple routers to work together as a single virtual router, providing redundancy and failover capabilities in case of a failure.
  • Virtual Router Redundancy Protocol (VRRP): VRRP is a similar protocol to HSRP that allows multiple routers to work together as a single virtual router. It also provides redundancy and failover capabilities.
  • Link Aggregation Control Protocol (LACP): LACP allows multiple physical links to be bundled together to form a single logical link, providing increased bandwidth and redundancy.
  • Cisco Express Forwarding (CEF) Switching: CEF is a high-performance switching technology that allows the router to forward packets quickly and efficiently, providing increased performance and scalability.
  • Dual Power Supplies: The C3925-VSEC-SRE/K9 supports dual power supplies, which allows the router to continue operating even if one power supply fails.
  • Dual Flash Memory: The router supports dual flash memory, which allows the router to continue operating even if one flash memory fails.
  • Redundant Management: The router supports redundant management, which allows the router to continue operating even if one management interface fails.

These high-availability and redundancy features allow the C3925-VSEC-SRE/K9 to provide a high level of reliability and availability, ensuring that networks are always available and running smoothly.

Advanced Encryption and Authentication

The Cisco 3925 SRE Bundle Integrated Services Router (C3925-VSEC-SRE/K9) offers advanced encryption and authentication capabilities to help secure networks and remote users. These features include:

  • Advanced Encryption Standard (AES) and Secure Hash Algorithm (SHA) encryption: The router supports AES and SHA encryption algorithms, which provide strong encryption for data in transit.
  • Internet Key Exchange version 2 (IKEv2): The router supports IKEv2, which allows for secure key management and negotiation for VPN connections.
  • Secure Sockets Layer (SSL) and Transport Layer Security (TLS) encryption: The router supports SSL and TLS encryption protocols, which are commonly used to secure web-based applications and services.
  • Public Key Infrastructure (PKI) support: The router supports PKI, which allows for secure certificate-based authentication and encryption.
  • Two-factor authentication: The router supports two-factor authentication, which requires users to provide two forms of identification, such as a password and a security token, to gain access to network resources.
  • Extensible Authentication Protocol (EAP) support: The router supports EAP, which allows for secure authentication of wireless clients.
  • Access Control Lists (ACLs): The router supports ACLs, which allow network administrators to control access to network resources based on user or device attributes.

These advanced encryption and authentication features allow the C3925-VSEC-SRE/K9 to provide a high level of security for networks and remote users, while also enabling secure and reliable remote access.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

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.

Important Features

Multi-core Processor

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.

Multi-band options

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 5 GHz.

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, cyber criminals 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.
