Study Notes

Basic Router Configuration

Configure devices and verify connectivity.
Display router information.

IP Routing Table Overview

Contains routes to known networks including prefixes and prefix lengths.
Information sources include:
- Directly connected networks.
- Static routes.
- Dynamic routing protocols.

Route Source Codes

L: Identifies address assigned to a router interface.
C: Identifies a directly connected network.
S: Identifies a static route for specific network access.
O: Identifies a dynamically learned network using OSPF protocol.
*: Indicates a candidate for a default route.

Routing Table Principles

Proper configuration of static and dynamic routing resolves issues affecting path determination between source and destination devices.

Path Determination Functions

Routing: Decides which interface to forward an IP packet to reach its destination.
Forwarding: Moves packets either to the destination directly or through intermediate routers.

Static Routes

Manually configured paths between networks.
Not automatically updated; require reconfiguration with topology changes.
Uses in small networks:
- Simplifies route management.
- Employs a default route for unmatched destinations.
- Essential for routing to and from stub networks, accessed via a single neighbor.

Static Routes in IP Routing Table

Example shown with IPv4 and IPv6 static routes configured on R1 to reach specific networks on R2.

Dynamic Routing Protocols

Allow routers to automatically share reachability and status of remote networks.
