Chapter 4 Configuring the Router

Performing the Initial Configuration on the Router

Examples

Specifying a Default Route: Example

!

ip routing

!

ip route 192.168.24.0 255.255.255.0 172.28.99.2

!

ip default-network 192.168.24.0

!

Sample Output for the show ip route Command

Router# show ip route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

i- IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default Gateway of last resort is 172.28.99.2 to network 192.168.24.0

Configuring Virtual Terminal Lines for Remote Console Access

Virtual terminal (vty) lines are used to allow remote access to the router. This section shows you how to configure the virtual terminal lines with a password, so that only authorized users can remotely access the router.

The router has five virtual terminal lines by default. However, you can create additional virtual terminal lines as described in Cisco IOS Terminal Services Configuration Guide, Release 12.4. See http://www.cisco.com/en/US/docs/ios/termserv/configuration/guide/tsv_term_op_char_dialin_ps6350_ TSD_Products_Configuration_Guide_Chapter.html.

Line passwords and password encryption is described in the Cisco IOS Security Configuration Guide, Release 12.4. See http://www.cisco.com/en/US/docs/ios/security/configuration/guide/12_4/sec_12_4_book.pdf.

Note To secure the vty lines with an access list, see http://www.cisco.com/en/US/products/index.html

OL-31454-01 specifications

Cisco Systems OL-31454-01 refers to a specific configuration guide for Cisco networking equipment, which serves an essential role in helping IT professionals understand how to deploy and manage their networking hardware efficiently. This document is particularly relevant for those working with Cisco routers and switches, highlighting various features, technologies, and best practices in network management.

A core feature of Cisco Systems OL-31454-01 is its focus on enhancing network performance and reliability. The systems typically include advanced Quality of Service (QoS) mechanisms, ensuring that critical applications receive the necessary bandwidth and performance even during peak usage times. This is crucial for enterprises that rely on uninterrupted access to applications and services.

The guide also discusses technologies such as VLANs (Virtual Local Area Networks), which allow network administrators to segment networks for improved performance and security. By isolating traffic within different VLANs, organizations can mitigate congestion and enhance overall network efficiency.

Another critical aspect of OL-31454-01 is its in-depth look at security features. Cisco networking solutions typically come equipped with integrated security protocols, such as IPsec for Virtual Private Networks (VPNs) and advanced threat detection mechanisms. This layered approach to security helps protect sensitive data from unauthorized access and cyber threats.

Furthermore, the guide emphasizes the importance of automation and programmability in modern networks. Utilizing Cisco's software-defined networking (SDN) capabilities, network engineers can automate various tasks, reducing the potential for human error and freeing up valuable resources. The integration of tools like Cisco DNA Center provides a unified network management platform, enhancing visibility and control across the entire network.

In addition to these features, Cisco Systems OL-31454-01 outlines various compatibility options with existing technologies and infrastructure. The guide ensures that IT teams can seamlessly integrate new hardware into their current networks without significant overhauls, facilitating a more efficient transition.

Overall, OL-31454-01 serves as a comprehensive resource for deploying and managing Cisco systems, offering valuable insights into essential features, technologies, and best practices that can significantly enhance an organization's networking capabilities.
