Configuring Routing and Advanced Switching

These flashcards cover key terminology and concepts related to routing and advanced switching, primarily focusing on the configuration and operation of networks.

Routing Table

An internal map used by routers to guide data packets to their destinations.

Dynamic Routing Protocols

Algorithms that automatically update route information and adjust paths between network nodes.

Network Address Translation (NAT)

Modifies network address information in packet headers to allow multiple devices to share a single public IP address.

VLAN (Virtual LAN)

Creates separate networks within a single physical network infrastructure.

Static Route

A manually added route that only changes if edited by the administrator.

Routing Entry Parameters

Include protocol, destination, interface, and gateway/next hop.

Traceroute

A tool that tracks a packet’s path to its destination.

Edge Router

Located at the boundary of a network, manages the flow of data between internal and external networks.

Tagged Ports

Ports configured to receive packets that have a VLAN identifier.

Untagged Ports

Ports set to receive data without a VLAN identifier.

Hop Count

A metric used by the RIP protocol to find the best path between source and destination.

Distance-Vector Protocol

A type of routing protocol that calculates the best path based on distance metrics.

Link-State Protocol

A routing protocol that transmits complete routing information to every router on the network.

Native VLAN

The VLAN that receives all untagged frames.

Three-Tiered Network Hierarchy

A network design that consists of core, distribution, and access layers.

Traceroute

Network Address Translation (NAT)

Translates between private and public IP addresses for internet access.

VLAN (Virtual LAN)

Creates separate logical network segments within a single physical network.

Native VLAN

The VLAN that receives all untagged frames.

Tagged Port

Ports configured to receive packets that have a VLAN identifier.

Untagged Port

Ports set to receive data without a VLAN identifier.

Edge Router

Located at the boundary of a network

Three-Tiered Network Hierarchy

A network design that consists of core

Static NAT

One-to-one mapping between private and public IP addresses.

Dynamic NAT

Maps multiple private IPs to a pool of public IP addresses.

PAT (Port Address Translation)

Maps multiple private IPs to a single public IP using different ports.

Core Layer

High-speed backbone; forwards traffic between distribution layers.

Distribution Layer

Routes traffic between VLANs; implements policies.

Access Layer

Connects end devices; provides VLAN segmentation.
