Network Fundamentals

The network fundamentals section of the CCNA 200-125 book covers the basics of networking, including the OSI model, TCP/IP, and network topologies. The book provides an in-depth look at each layer of the OSI model, including the physical, data link, network, transport, session, presentation, and application layers. The book also covers TCP/IP, including IP addressing, subnetting, and routing.

OSI Model

The OSI model is a seven-layer model that defines how data is transmitted over a network. Each layer of the model has a specific function, and data passes through each layer as it is transmitted from one device to another. The physical layer is responsible for transmitting bits over a physical medium, while the data link layer is responsible for framing data and providing error detection. The network layer is responsible for routing data between networks, while the transport layer is responsible for end-to-end communication. The session layer is responsible for establishing and managing sessions between devices, while the presentation layer is responsible for data representation and encryption. The application layer is responsible for providing services to applications.

TCP/IP

TCP/IP is a suite of protocols that is used for communication over the Internet. TCP/IP consists of several protocols, including IP, TCP, and UDP. IP is responsible for routing data between networks, while TCP provides reliable, connection-oriented communication between devices. UDP provides unreliable, connectionless communication between devices.

LAN Switching Technologies

The LAN switching technologies section of the CCNA 200-125 book covers VLANs, STP, and EtherChannel. VLANs allow network administrators to segment their networks into smaller, more manageable subnets. STP is used to prevent loops in redundant network topologies, while EtherChannel allows multiple physical links to be combined into a single logical link.

VLANs

VLANs are logical subnets that are created within a physical network. VLANs allow network administrators to segment their networks based on function or department, which can improve network performance and security. VLANs are created using software, and devices on different VLANs cannot communicate with each other unless a router is used.

STP

STP is a protocol that is used to prevent loops in redundant network topologies. STP works by selecting a root bridge, which is the central point of the network, and blocking redundant links to prevent loops. If a link fails, STP will automatically reconfigure the network to use an alternate path.

EtherChannel

EtherChannel allows multiple physical links to be combined into a single logical link. This can improve network performance and redundancy. EtherChannel is configured on both ends of the link, and all physical links must have the same speed and duplex settings.

Routing Technologies

The routing technologies section of the CCNA 200-125 book covers OSPF, EIGRP, and BGP. OSPF is a link-state routing protocol that is used for internal routing within an organization. EIGRP is a distance-vector routing protocol that is used for small to medium-sized networks. BGP is an external routing protocol that is used for connecting to the Internet.

OSPF

OSPF is a link-state routing protocol that is used for internal routing within an organization. OSPF uses a hierarchical structure, with areas that are connected by a backbone area. OSPF routers exchange link-state advertisements (LSAs) to build a map of the network, which is used to calculate the best path to a destination.

EIGRP

EIGRP is a distance-vector routing protocol that is used for small to medium-sized networks. EIGRP uses a metric called the composite metric, which takes into account bandwidth, delay, reliability, load, and MTU. EIGRP routers exchange routing updates to build a table of routes, which is used to forward packets to their destinations.

BGP

BGP is an external routing protocol that is used for connecting to the Internet. BGP is a path-vector protocol, which means that it selects the best path to a destination based on a set of attributes, such as AS path length, local preference, and MED. BGP routers exchange routing updates to build a table of routes, which is used to forward packets to their destinations.

WAN Technologies

The WAN technologies section of the CCNA 200-125 book covers PPP, Frame Relay, and VPNs. PPP is a protocol that is used for point-to-point communication over serial links. Frame Relay is a packet-switching technology that is used for connecting multiple sites over a wide area network. VPNs are secure connections that are used to connect remote sites or users to a central network.

PPP

PPP is a protocol that is used for point-to-point communication over serial links. PPP provides authentication, compression, and error detection. PPP uses a three-stage process to establish a connection: link establishment, authentication, and network layer protocol negotiation.

Frame Relay

Frame Relay is a packet-switching technology that is used for connecting multiple sites over a wide area network. Frame Relay uses virtual circuits to connect sites, and each virtual circuit has a unique DLCI. Frame Relay supports two types of virtual circuits: permanent virtual circuits (PVCs) and switched virtual circuits (SVCs).

VPNs

VPNs are secure connections that are used to connect remote sites or users to a central network. VPNs use encryption to protect data as it is transmitted over the Internet. VPNs can be either site-to-site or remote access, depending on the type of connection.

Network Services

The network services section of the CCNA 200-125 book covers DHCP, NAT, and QoS. DHCP is a protocol that is used to automatically assign IP addresses to devices on a network. NAT is a technique that is used to translate private IP addresses to public IP addresses. QoS is a set of techniques that is used to prioritize traffic on a network.

DHCP

DHCP is a protocol that is used to automatically assign IP addresses to devices on a network. DHCP uses a client-server model, with the DHCP server assigning IP addresses to clients. DHCP also provides other configuration information, such as DNS server and default gateway addresses.

NAT

NAT is a technique that is used to translate private IP addresses to public IP addresses. NAT is used when a network does not have enough public IP addresses to assign to all of its devices. NAT can be either static or dynamic, depending on whether the mapping between private and public IP addresses is fixed or changes over time.

QoS

QoS is a set of techniques that is used to prioritize traffic on a network. QoS can be used to ensure that critical applications, such as voice and video, receive sufficient bandwidth and are not affected by other traffic on the network. QoS techniques include traffic shaping, queuing, and classification.

Network Security

The network security section of the CCNA 200-125 book covers firewalls, VPNs, and intrusion prevention systems. Firewalls are used to protect networks from unauthorized access, while VPNs are used to provide secure connections over the Internet. Intrusion prevention systems are used to detect and prevent attacks on a network.

Firewalls

Firewalls are used to protect networks from unauthorized access. Firewalls can be either hardware or software-based, and they can use a variety of techniques to block unauthorized traffic, such as packet filtering, stateful inspection, and application-layer filtering.

VPNs

VPNs are used to provide secure connections over the Internet. VPNs use encryption to protect data as it is transmitted over the Internet. VPNs can be either site-to-site or remote access, depending on the type of connection.

Intrusion Prevention Systems

Intrusion prevention systems are used to detect and prevent attacks on a network. Intrusion prevention systems use a variety of techniques to detect and block attacks, such as signature-based detection, anomaly-based detection, and behavior-based detection.
