Introduction to the 2851 Series Router
The CISCO2851-HSEC-K9 Cisco 2851 Security Bundle Router is a high-performance, multi-purpose router designed for small and medium-sized businesses, enterprise branch offices, and service provider environments. The router is part of the Cisco 2800 series, which is known for its high-performance routing, security, and voice capabilities.
One of the main features of the CISCO2851-HSEC-K9 is its ability to provide high-security encryption for VPN connections. The router is equipped with a security bundle that includes an integrated hardware-accelerated VPN encryption module, which supports up to 500 VPN tunnels. This makes the router ideal for organizations that need to securely connect remote offices or mobile workers to their corporate network.
The CISCO2851-HSEC-K9 also supports a wide range of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP). This allows the router to easily connect to other networks and provide efficient routing for data traffic.
In terms of voice capabilities, the CISCO2851-HSEC-K9 supports Voice over IP (VoIP) and can be configured with a variety of voice interfaces, such as FXS and FXO ports, to connect to traditional telephone systems. The router also supports advanced voice features such as call routing, voicemail, and conferencing.
The router is also equipped with a variety of management and monitoring features, including a web-based graphical user interface (GUI), command-line interface (CLI), and Simple Network Management Protocol (SNMP) support. This allows administrators to easily configure, monitor, and troubleshoot the router.
Advanced Security Features
The CISCO2851-HSEC-K9 Cisco 2851 Security Bundle Router provides a comprehensive set of advanced security features to help protect your network from a wide range of threats. Some of the key advanced security features of this router include:
- Hardware-accelerated VPN encryption: The router is equipped with an integrated hardware-accelerated VPN encryption module that supports up to 500 VPN tunnels. This allows for secure connectivity between remote offices and mobile workers and the corporate network.
- Firewall: The router includes a stateful inspection firewall that can be configured to block unauthorized access and protect against various types of network-based attacks.
- Intrusion Prevention System (IPS): The router includes an IPS feature that can detect and prevent network intrusions in real-time.
- Network Address Translation (NAT): The router supports NAT, which allows you to share a single IP address among multiple devices on your network, making it more difficult for external parties to identify and target specific devices.
- Quality of Service (QoS): The router supports QoS, which allows you to prioritize different types of network traffic and ensure that important traffic, such as VoIP, is given priority over less important traffic.
- Advanced routing protocols: The router supports a wide range of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP) which allows for efficient routing of data traffic.
- Authentication, Authorization and Accounting (AAA) support: The router supports AAA, which allows for centralized management of user authentication, authorization, and accounting.
Establishing Internet Connectivity
Establishing internet connectivity on the CISCO2851-HSEC-K9 Cisco 2851 Security Bundle Router involves configuring the router's WAN (Wide Area Network) interface with the appropriate settings for your internet connection. The specific steps for establishing internet connectivity will vary depending on the type of internet connection you have (e.g. DSL, cable, etc.) and the settings provided by your internet service provider (ISP). However, in general, the steps for establishing internet connectivity will involve the following:
- Connect the router's WAN interface to your internet connection. This may involve connecting an Ethernet cable from your modem or other internet connection device to the router's WAN port.
- Configure the router's WAN interface with the appropriate IP address, subnet mask, and default gateway settings provided by your ISP.
- Configure the router's WAN interface with the appropriate DNS server settings provided by your ISP.
- Configure the router's WAN interface with the appropriate login credentials provided by your ISP.
- Verify that the router's WAN interface has obtained an IP address and that it is able to communicate with the internet. You can use the "show ip interface brief" command to check the status of the router's interfaces and ensure that the WAN interface is up and has an IP address.
- Configure the router's firewall and other security features to allow internet traffic to pass through.
- Configure the router's routing protocol to route traffic to the internet
Keep in mind that these are general steps, and the specific configurations may vary depending on your specific internet service provider and the type of internet connection you have. It's recommended to refer to the Cisco official documentation for more detailed instructions and configurations.

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.
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.
