Overview/Description
FHRP is a category of protocols that includes HSRP, as well as VRRP and GLBP. All three protocols have versions that support first-hop redundancy not only in IPv4 environments, but also in IPv6 environments. However, not all platforms and their Cisco IOS versions support all of these three protocols for both IPv4 and IPv6. In this course you'll learn how to configure and verify VRRP and GLBP. You'll also learn how to configure and verify GLBP in an IPv6 environment. This course offers the official training for the Implementing Cisco IP Switched Networks 2.0 certification...
Overview/Description
Campus access devices and Layer 2 communication are largely unconsidered in most security discussions; Equipment malfunction and internal malicious attacks can also bring down your network. In this course you will learn about private VLANs are used to help segment traffic within a single VLAN and how VLAN access lists can aid in your efforts of having a secure and stable network. This course offers the official training for the Implementing Cisco IP Switched Networks 2.0 certification exam which is a component exam for the CCNP and CCDP certifications. Passing this exam...
Overview/Description
Smooth operation and high availability of the network are crucial to organizations. Unplanned downtime can quickly lead to loss of productivity and, therefore, financial loss. To maximize the availability of the network, it is important to plan network maintenance processes and procedures carefully. Troubleshooting is a part of network maintenance that every network engineer needs to be capable of performing. In complex environments, troubleshooting can be a daunting task, and the only way to diagnose and resolve problems quickly and effectively is by following a...
Overview/Description
When troubleshooting IP addressing and routing issues, you might need to determine a client's IPv4, IPv6, and MAC addresses. The method of obtaining this addressing varies with operating system. There are a number of ways in which to assign IP addresses to devices throughout the network as well as numerous ways to verify an address depending on issue at hand. This course describes the ways in which to assign IPv4 and IPv6 addresses to various hosts as well as how to troubleshoot the various IP address assignment methods. Troubleshooting IPv4 and IPv6 basic routing is...
Overview/Description
IP routing is the core technology deployed in all current enterprise networks and is used in all areas of the network. For most connectivity problems in IP networks, the network layer is the point where troubleshooting processes start. The Open Shortest Path First (OSPF) protocol is a routing protocol commonly used in large enterprise networks. Troubleshooting problems related to the exchange of routing information is an essential skill for any network engineer that is involved in the implementation and maintenance of large routed enterprise networks that use OSPF as the...
Overview/Description
Enhanced Interior Gateway Routing Protocol (EIGRP) is a routing protocol commonly used in large enterprise networks. Troubleshooting problems related to the exchange of routing information is an essential skill for any network engineer that is involved in the implementation and maintenance of large routed enterprise networks that use EIGRP as the IGP. Enterprise networks may make use of the Border Gateway Protocol (BGP) to exchange routing information in a controlled fashion with external parties such as Internet service providers or other providers of IP-based services...
Overview/Description
Dynamic routing protocols such as RIPv2 play an important role in the enterprise networks of today. RIPv2 is one of several different protocols available, with each having its advantages and limitations. Having the ability to diagnose and resolve routing protocol operational issues are important skills for any network support engineer. This course reviews RIPv2 operations and the use of Cisco IOS commands to gather information about RIPv2 operations and routing processes, as well as the implementation of solutions for various issues that can occur.

Overview/Description
Dynamic routing protocols such as RIPng play an important role in the enterprise networks of today. RIPng is used for routes in IPv6 networks and as a support engineer, it is important to understand how to diagnose and resolve RIPng routing protocol operational issues. This course reviews RIPng operations and the use of Cisco IOS commands to gather information about RIPng operations and routing processes as well as the implementation of solutions for various issues that can occur.

Overview/Description
Ideally, a single routing protocol is used to exchange routing information in an enterprise network. However, organizational requirements such as partnerships, mergers, technology migrations, and changes in policy can make it necessary to support the use of multiple routing protocols in the same enterprise network. In such situations, route redistribution between the different routing protocols is often necessary to achieve IP connectivity between the different parts of the network, and this adds an extra layer of complexity to a routed network. As a support engineer, it...
Overview/Description
Switched Ethernet has been the dominant LAN technology for more than a decade and VLAN-based switched infrastructures are at the core of every campus network. A good understanding of the processes involved in Layer 2 switching and being able to diagnose and resolve Layer 2 switching problems in those environments is a fundamental skill that any network engineer should have. A primary tool in building highly available networks is the use of redundant devices and links. With these redundant links, bridging loops can be introduced, resulting in broadcast storms that can...
