CCNA Exploration 2 - Chapter 5
RIP version 1 is a classful distance vector routing protocol that uses hop count as its metric. It sends routing updates every 30 seconds and considers routes with a hop count greater than 15 to be unreachable. It performs automatic summarization which reduces the size of routing updates but does not support discontiguous subnets. Common commands to configure and verify RIP include router rip, network, show ip protocols, and debug ip rip.
CCNA Exploration 2 - Chapter 4
The document discusses distance vector routing protocols. It describes how they work by maintaining routing tables using periodic updates that contain the entire routing table. Distance vector protocols can be prone to routing loops during convergence but employ mechanisms like split horizon and holddown timers to prevent loops. Examples of distance vector protocols include RIP and EIGRP.
Exploration Lan Switching Chapter3
This document discusses VLANs and trunking in converged networks. It explains that VLANs logically group devices to segment broadcast domains, reducing costs and improving security and performance. Types of VLAN traffic include data, voice, and network protocols. Communication between VLANs requires routers.

The document also covers configuring and troubleshooting VLANs and trunks on Cisco switches.
CCNA Exploration 2 - Chapter 3
This document discusses dynamic routing protocols and concepts. It describes the functions of dynamic routing protocols as dynamically sharing information between routers, automatically updating routing tables when network topologies change, and determining the best path to destinations. It classifies routing protocols as either interior gateway protocols, used within autonomous systems, or exterior gateway protocols, used between autonomous systems. It also covers routing metrics, administrative distance, and the components of a routing table.
CCNA Exploration 2 - Chapter 11
This document provides an overview of the Open Shortest Path First (OSPF) routing protocol. It describes OSPF's basic features and configuration, including enabling OSPF, configuring network statements, examining the routing table, and modifying interface costs. It also covers OSPF operations in multi-access networks such as Designated Router election and flooding reduction techniques.
CCNA Exploration 2 - Chapter 6
The document discusses classful and classless IP addressing. With classful addressing, IP addresses are divided into classes based on the first octet, but this led to inefficient address usage. Classless Inter-Domain Routing (CIDR) was introduced to allow Variable Length Subnet Masking (VLSM) for more flexible subnetting. This allows networks to be divided into subnets of various sizes to better match addressing needs and allows routing to be summarized to reduce routing table sizes.
CCNA Exploration 2 - Chapter 10
Link-state routing protocols use Dijkstra's shortest path first (SPF) algorithm to determine the optimal path to all destinations. Each router uses hello packets to discover neighbors and then floods link state packets (LSPs) throughout the network, allowing every router to build a topological map and independently calculate the shortest path to each destination using SPF trees. Common link-state routing protocols are Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS).
CCNA 2 Routing and Switching v5.0 Chapter 7
This document discusses dynamic routing protocols and provides an overview of how they operate. It explains that dynamic routing protocols automatically share information about remote networks to determine the best path.

Objectives of the chapter are also listed, such as explaining dynamic routing operation and configuring RIP and OSPF protocols.
CCNA Exploration 2 - Chapter 2
This document discusses static routing and provides configuration examples. It covers defining router roles, examining directly connected networks, configuring static routes with next hop addresses or exit interfaces, summarizing routes, and troubleshooting routing issues. Static routes allow routers to forward packets to destination networks manually without a dynamic routing protocol. Route summarization and default routes reduce routing table sizes.

CCNA Exploration 1 - Chapter 7
This document outlines objectives and topics related to the data link layer in networking. It discusses the role of the data link layer in preparing data for transmission, different media access control methods, common network topologies, framing of packets, data link addressing, and ensuring reliable transmission. The key topics covered are how the data link layer controls access to shared media, encapsulates packets into frames, uses addressing to identify devices, and includes error checking in frames.
CCNA Exploration 3 - Chapter 3
This document discusses VLANs and trunking in converged networks. It covers the role of VLANs in segmenting broadcast domains and logically grouping devices. Trunks are used to allow communication between VLANs by tagging frames with the VLAN ID. The document provides instructions on configuring VLANs and trunks on Cisco switches using IOS commands, and troubleshooting common problems with VLAN and trunk configurations.
IPv6 DHCP
The document discusses DHCPv6 and how it can be implemented in stateful and stateless modes. In stateful mode, clients obtain IPv6 addresses and configuration from a DHCPv6 server.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
