Advanced Routing Protocols
The CISCO2951/K9 Cisco 2951 Integrated Services Router supports a variety of advanced routing protocols that can be used to improve the performance and scalability of the network. Some of the most commonly used advanced routing protocols for Cisco routers include:
- Border Gateway Protocol (BGP): BGP is a routing protocol used for exchanging routing information between routers in different autonomous systems (AS) on the Internet. It is the most widely used routing protocol for inter-domain routing and is particularly well-suited for service provider networks.
- Open Shortest Path First (OSPF): OSPF is a link-state routing protocol that is widely used in enterprise networks. It is a classless routing protocol, which means that it supports variable-length subnet masks (VLSMs) and can be used to summarize routes at different levels in the network.
- Enhanced Interior Gateway Routing Protocol (EIGRP): EIGRP is a Cisco-proprietary routing protocol that is similar to OSPF in its operation. EIGRP supports both IP and IPX protocols and is widely used in enterprise networks.
- Routing Information Protocol (RIP): RIP is a distance-vector routing protocol that is used to distribute routing information within a small to medium-sized network.
- Multiprotocol Label Switching (MPLS): MPLS is a mechanism that allows routers to forward packets based on a label, rather than the traditional IP destination address. MPLS is often used to provide virtual private network (VPN) services, as well as to improve the performance and scalability of service provider networks.
Management of Network Bandwidth
The CISCO2951/K9 Cisco 2951 Integrated Services Router can be used to manage the bandwidth of a network in several ways:
- Quality of Service (QoS): QoS is a set of technologies and techniques that can be used to prioritize different types of network traffic. By prioritizing certain types of traffic, such as voice or video, over less time-sensitive traffic, like file transfers or web browsing, QoS can help to ensure that important traffic gets through the network even when the network is congested.
- Traffic shaping: Traffic shaping is a technique that can be used to control the rate at which traffic is sent into a network. By controlling the rate at which traffic is sent into the network, administrators can prevent network congestion and ensure that the network is used efficiently.
- Link fragmentation and interleaving (LFI): LFI is a technique that can be used to increase the effective bandwidth of a link by fragmenting large packets into smaller ones and interleaving them with other traffic. This allows more packets to be sent over the link in a given amount of time, increasing the effective bandwidth of the link.
- Class-based weight fair queuing (CBWFQ): CBWFQ is a technique that can be used to manage bandwidth allocation by assigning different priority levels to different types of traffic. This allows administrators to ensure that important traffic, such as voice and video, gets priority over less important traffic, such as file transfers or web browsing.
- Access lists: Access lists can be used to limit the amount of bandwidth used by a specific host or group of hosts on a network. This can be useful for controlling the usage of bandwidth-intensive applications, such as video streaming or file transfers.
