Module 4 Routing Technologies & Load Balancing Review

These flashcards cover key concepts related to routing technologies and configurations in networking, focusing on static routing, dynamic routing protocols, and Cisco router configurations.

Routing

The process of moving a packet of data from source to destination.

Router

A specialized device that performs routing, reading headers of packets to determine their intended destination.

Static Routing

Routes are manually added to the routing table for security and efficiency, without routing overhead.

Default Routing

Configuration that sends all packets toward a single router, typically used by stub routers.

Dynamic Routing

Automatically adjusts routes based on the current state of the route in the routing table, utilizing protocols.

Cisco Packet Tracer

Network simulator software used to practice and configure Cisco routers and networks.

User Mode

Router mode with limited viewing of configurations, cannot make changes.

Privileged Mode

Router mode that allows user to see and modify configurations.

Global Configuration Mode

Router mode enabling the execution of configuration commands.

Interface Mode

Router mode to configure specific interfaces.

Static Route

A manually defined route in the routing table that doesn't change unless reconfigured.

RIP (Routing Information Protocol)

An interior gateway protocol used to exchange routing information within local networks.

EIGRP (Enhanced Interior Gateway Routing Protocol)

A Cisco proprietary routing protocol that combines features of distance vector and link-state protocols.

OSPF (Open Shortest Path First)

A link-state routing protocol that uses the SPF algorithm to maintain a loop-free topology.

Administrative Distance (AD)

A value used to rate the trustworthiness of a routing information source; lower values are preferred.

Hello Packets

Packets sent by EIGRP to maintain neighborship and discover neighbors.

Wildcard Mask

A mask used in OSPF to specify which IP addresses should match when configuring routing.

Subinterface

A logical division of a router interface that allows multiple logical interfaces on a single physical interface.

Login Banner

Message displayed on the console, typically for user information.

Message-of-the-Day (MOTD)

A banner message displayed before login prompts, useful for alerts or announcements.

Routing Table

A data table stored in a router or a networked computer that lists the routes to particular network destinations.
