The CISCO2851-SEC/K9 is a bundle of advanced security features for the Cisco 2851 router. It includes features such as VPN and firewall functionality, intrusion prevention, and advanced security management tools. The router also includes a variety of interfaces for connecting to different types of networks and devices, as well as support for various protocols and technologies. With the security bundle, the Cisco 2851 offers a comprehensive and robust solution for securing networks and protecting against a wide range of threats.
High Availability and Redundancy Options
The CISCO2851-SEC/K9 Cisco 2851 Security Bundle Router includes high availability and redundancy options to ensure that the router is always available and able to handle network traffic. These options include:
- Hot Standby Router Protocol (HSRP): This protocol allows two routers to work together to provide redundancy in case one of them fails. One of the routers is designated as the active router, while the other is in standby mode. If the active router fails, the standby router takes over and becomes the active router.
- Virtual Router Redundancy Protocol (VRRP): similar to HSRP, this protocol allows multiple routers to work together to provide redundancy. One of the routers is designated as the master, while the others are in backup mode. If the master fails, one of the backups takes over as the master.
- Cisco Express Forwarding (CEF) Switchover: This feature allows the router to quickly switch over to a secondary forwarding table in case of a failure, reducing downtime and ensuring that network traffic continues to flow smoothly.
- Redundant Power Supply: The router can have a second power supply as backup in case the primary one fails.
These High Availability and Redundancy options of CISCO2851-SEC/K9 helps to ensure that the router is always available and able to handle network traffic, thereby reducing downtime and ensuring that network traffic continues to flow smoothly.
Performance and Throughput Capabilities
The CISCO2851-SEC/K9 Cisco 2851 Security Bundle Router is a powerful and high-performance router that offers a variety of performance and throughput capabilities. Some of its key capabilities include:
- High-speed data processing: The router is equipped with a multi-core processor, which allows it to handle large amounts of data traffic quickly and efficiently.
- High-speed routing and switching: The router supports high-speed routing and switching protocols, such as Multi-Protocol Label Switching (MPLS) and Quality of Service (QoS), which allow it to handle large amounts of data traffic and prioritize different types of traffic for optimal performance.
- High-speed VPN support: The router supports advanced VPN technologies, such as IPsec, SSL, and L2TP, which allow it to securely transmit data over public networks at high speeds.
- High-speed WAN interfaces: The router supports a variety of WAN interfaces, such as T1/E1, T3/E3, and OC-3/STM-1, which allow it to connect to different types of networks and support high-speed data transfer.
- High-speed LAN interfaces: The router supports a variety of LAN interfaces, such as Ethernet and Fast Ethernet, which allow it to connect to different types of devices and support high-speed data transfer.
These performance and throughput capabilities of CISCO2851-SEC/K9 allows it to handle large amounts of data traffic, prioritize different types of traffic for optimal performance, and support high-speed connections to different types of networks and 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.
