Cisco ROUTE 1.0: Configuring and Verifying Route Redistribution

Overview/Description Routing updates compete with user data for bandwidth and router resources, yet routing updates are critical because they carry the information that routers need to make sound routing decisions. To ensure that a network operates efficiently, you must know how to control and tune routing updates. Since there is no one type of route filter that is appropriate for every situation, the more techniques that you have at your disposal, the better your chance of having a smooth, well-run network. Simple routing protocols work well for simple networks, but as networks grow and...

Cisco ROUTE 1.0: Connecting the Enterprise to ISPs

Overview/Description The Internet has become a vital resource in many organizations, and the Border Gateway Protocol (BGP) is an alternative to using default routes to control path selections. Before the connection of an enterprise network to an Internet service provider (ISP) can be implemented, planning needs to be completed. To plan for connectivity to an ISP properly, the network designer must take into account certain details. This course provides the knowledge required to implement enterprise-to-ISP connectivity. This includes an understanding of the types of session origination points...

Cisco ROUTE 1.0: EIGRP Authentication and Advanced Feature Implementation

Overview/Description Security is an important part of any network and should be extended to the routing protocol by implementing neighbor authentication. Without this authentication, unauthorized or deliberately malicious routing updates can compromise the security of network traffic. EIGRP neighbor authentication can be configured in such a way that routers can participate in routing based on predefined passwords. EIGRP is a scalable routing protocol, which ensures that as a network grows larger, it operates efficiently and adjusts rapidly to changes. It is important as a Cisco administrator...

Cisco ROUTE 1.0: EIGRP Implementation for the Enterprise

Overview/Description In routing environments, Enhanced Interior Gateway Routing Protocol (EIGRP) offers benefits and features over historical distance-vector routing protocols such as Routing Information Protocol version 1 (RIPv1). These benefits include rapid convergence, lower bandwidth utilization, and multiple routed protocol support besides IP. As an administrator, understanding the EIGRP commands used to configure a router is essential, especially during initial configuration or routing protocol migration. EIGRP can also operate over various underlying network technologies – Ethernet...

Cisco ROUTE 1.0: Implementing an OSPF-Based Solution

Overview/Description Configuring Open Shortest Path First (OSPF) in today's networks is an important skill to have as a network administrator. You will need to understand the primary configuration commands for single-area and multiarea OSPF designs, and the commands used to verify configurations. OSPF presents some design limitations, but offers up solutions for each. Scalability, improved CPU and memory utilization, and the ability to mix small routers with large routers are all benefits of using proper route summarization techniques which is a key feature of OSPF. An OSPF network can scale...

Cisco ROUTE 1.0: Implementing Path Control

Overview/Description Policy-based routing allows administrators to route traffic along specific paths according to their needs and gives you greater flexibility in determining traffic patterns and best routes. Sometimes, simple destination-based routing is not sufficient, so in these cases you may route packets based on source address, protocol type, or application type so that they can optimally shape traffic patterns. As an administrator, understanding the collection of tools, or set of commands, that are used to manipulate the routing protocol forwarding table, and bypass the default...

Cisco ROUTE 1.0: Routing Services for Converged Networks

Overview/Description The convergence of voice, video, and data has not only changed the conceptual network models but has also affected the way that networks support services and applications. Planning routing services to support requirements requires an understanding of the Cisco Enterprise Architectures and how they align with the traditional three-layer hierarchical network model. Understanding of the network traffic moving throughout the architecture is also important. To create an implementation plan, you must have detailed network information, tools, resources, and a work plan. By...

Cisco ROUTE 1.0: The OSPF Routing Protocol

Overview/Description Open Shortest Path First (OSPF) is one of the most commonly used IP routing protocols in today's networks. It is an open standard that is used by both enterprise and service provider networks. OSPF has several functions and five packet types to enable all OSPF information flow between routers. OSPF areas may be made up of different types of network links and it is vital that you know which ones are being used in order to properly configure OSPF. It is equally important to note that OSPF pays special attention to different network types, such as point-to-point and...

Cisco SECURE 1.0: Advanced Control Plane Security Controls

Overview/Description The control plane in an Open Systems Interconnection (OSI) Layer 3 device provides traffic routing functions by building the device routing and forwarding tables. This often involves cooperation with nearby devices using dynamic routing protocols. These interactions must be controlled in multiple aspects by authenticating the associations between devices, discarding malicious routing information, and protecting the resources of each device against excessive use. This course examines a number of defenses in Cisco IOS Software that protect the control plane: infrastructure...

Cisco SECURE 1.0: Advanced Routed Data Plane Security Controls

Overview/Description In an Open Systems Interconnection (OSI) Layer 3 device, the data plane implements the packet forwarding functions and applies services to packets as they are forwarded through the device. The routed data plane can provide various OSI Layer 3 traffic filtering and traffic telemetry services to protect both the network infrastructure and the endpoints that are connected to the network. This course introduces some effective tools that you can use to provide such protection. Target Audience Network professionals responsible for securing and managing their network...
