Description
Advanced Routing Protocols
The Cisco 819G router supports several advanced routing protocols, including:
- Border Gateway Protocol (BGP) is a routing protocol that is used to exchange routing information between routers in different autonomous systems (AS) on the Internet. BGP is considered a path vector protocol and is used to create a mesh of routing information between networks. BGP is typically used by service providers and large enterprises to connect their networks to the Internet.
- Open Shortest Path First (OSPF) is a routing protocol that is used to distribute routing information within a single autonomous system (AS). OSPF is a link state protocol, which means that it maintains a database of the state of the network’s links and uses this information to calculate the shortest path to a destination. OSPF is commonly used in enterprise networks.
- Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco proprietary routing protocol that is similar to OSPF in terms of functionality and operation. EIGRP uses advanced metrics to calculate the best path to a destination and also supports multiple network protocols. EIGRP is also used in enterprise networks.
- Routing Information Protocol (RIP) is a distance-vector routing protocol that is used to distribute routing information within a single autonomous system. RIP uses the hop count as a metric to determine the best path to a destination. It is a simple and easy to use protocol but it has limitations, such as a maximum hop count of 15, which limits its use to smaller networks.
- Static routing is a manual configuration of routes that do not change unless manually modified. Static routing is simple to configure and does not require any additional resources or processing power. It is commonly used in small networks or as a backup for dynamic routing protocols.
Remote Access VPN Solutions
The Cisco 819G router supports several remote access VPN solutions, including:
- Cisco IOS Software VPN: This solution supports various VPN protocols, such as Internet Key Exchange version 2 (IKEv2), Secure Sockets Layer (SSL), and Internet Protocol Security (IPsec). It allows for secure remote access to the network for remote employees and partners.
- Easy VPN (EZVPN): This is a Cisco IOS Software VPN solution that simplifies the configuration and deployment of VPNs. It allows for secure remote access to the network for remote employees and partners.
- Cisco AnyConnect Secure Mobility Client: This is a software-based VPN client that provides secure remote access to the network for remote employees and partners. It supports various VPN protocols, such as IKEv2, SSL, and IPsec.
- Cisco VPN Client: This is a software-based VPN client that allows for secure remote access to the network for remote employees and partners. It supports various VPN protocols, such as IKEv2, SSL, and IPsec.
Quality of Service (QoS) Capabilities
The Cisco 819G router supports various Quality of Service (QoS) capabilities, which allow for the prioritization of different types of traffic on the network. These capabilities include:
- Class-Based Weighted Fair Queuing (CBWFQ): This allows for the prioritization of different types of traffic based on their class, with higher priority classes receiving more bandwidth.
- Low Latency Queuing (LLQ): This allows for the prioritization of delay-sensitive traffic, such as voice and video, over other types of traffic.
- Priority Queuing (PQ): This allows for the prioritization of specific types of traffic, such as voice and video, over other types of traffic.
- Weighted Random Early Detection (WRED): This allows for the random dropping of lower priority traffic in order to prevent network congestion.
- Traffic Shaping: This allows for the control of the rate at which traffic is sent out, helping to prevent network congestion.
- Class-Based Marking (CB Marking): This allows for the marking of packets with a specific class, allowing them to be prioritized in downstream devices
