Description
High-Availability and Redundancy Features
The CISCO2851-CCME/K9 Cisco 2851 Voice Bundle Router provides a range of high-availability and redundancy features to ensure that the network remains operational even in the event of hardware or software failures.
One of the key features is support for Cisco’s IOS-XE Software which allows for the configuration of multiple software images on the router and the ability to switch between them in the event of a software failure. This ensures that the network remains operational even if the primary software image fails.
The router also supports Stateful Switchover (SSO) feature which allows for seamless failover between the router’s active and standby processors in the event of a hardware failure. This ensures that the network remains operational even if the primary processor fails.
Additionally, the router supports redundancy at the power supply level, which allows for the installation of a redundant power supply to take over in the event of a failure of the primary power supply.
In terms of software redundancy, the router supports a number of protocols such as Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) which allows for redundancy at the network layer.
The router also includes support for Cisco’s Advanced Gateway Redundancy Protocol (AGRP) which ensures that the router can continue to provide services even in the event of a failure of one of the routers in the cluster.
Security and Firewall Features
The CISCO2851-CCME/K9 Cisco 2851 Voice Bundle Router includes a variety of security and firewall features to protect the network from unauthorized access and potential threats.
One of the key security features is the built-in firewall, which provides stateful packet inspection (SPI) and allows for the configuration of access control lists (ACLs) to control the flow of traffic in and out of the network. The router also supports Cisco’s Network Admission Control (NAC) feature, which allows for secure access to the network based on a user’s identity and security posture.
The router also includes support for Virtual Private Network (VPN) functionality, which allows for secure communication between remote sites and users. It supports a variety of VPN protocols such as IPsec, L2TPv3, and FlexVPN.
The router also includes support for intrusion prevention system (IPS) which can detect and block malicious traffic. Additionally, the router supports Cisco’s Security Group Tag (SGT) feature which allows for the enforcement of security policies based on user identity.
The router also includes support for various security protocols such as SSH, SSL, and HTTPS for secure management and access.
Cisco also includes Cisco IOS Firewall feature set as part of the security features of CISCO2851-CCME/K9, this allow to implement advanced firewall policies, and includes features like Zone-based firewall, Application inspection, and Control Plane Policing.
Best Practices and Configuration Examples
The CISCO2851-CCME/K9 Cisco 2851 Voice Bundle Router is a versatile router that can be configured to meet the specific needs of a variety of different network environments. There are several best practices and configuration examples that can be used to help ensure that the router is configured and optimized for optimal performance and security.
One of the best practices for configuring the router is to segment the network using VLANs. This allows for the creation of separate broadcast domains, which can help to improve security and reduce network congestion.
Another best practice is to configure Quality of Service (QoS) to prioritize voice and video traffic over other types of traffic. This can be done by using features such as Class-Based Weighted Fair Queuing (CBWFQ) and Low Latency Queuing (LLQ) to ensure that voice and video traffic is given priority over other types of traffic.
Another best practice is to implement a firewall and access control lists (ACLs) to control the flow of traffic in and out of the network, and to use Network Admission Control (NAC) to ensure that only authorized users are able to access the network.
In addition, it is recommended to configure Virtual Private Network (VPN) to allow for secure communication between remote sites and users and to implement Intrusion Prevention System (IPS) and Security Group Tag (SGT) to detect and block malicious traffic.
It is also recommended to monitor the network regularly to ensure that it is running efficiently and to identify and troubleshoot any issues that may arise.
