2
Hardware Configuration of Cisco Router
  • Cisco 2500 Series (2522, 2524)

Ref http//www.cisco.com/univercd/cc/td/doc/pcat/
2500.htm
3
Cisco 2500 Router Series - Hardware (Memory)
  • Dynamic Random-Access Memory (DRAM) for main
    memory (store the operating configuration,
    routing tables, caches, and queues. 2M-14M ) and
    shared memory (store incoming and outgoing
    packets. 2M)
  • Flash memory for running the Cisco IOS software
    (8M, 4M for mission specific)

4
Cisco 2500 Router Series- Hardware (Processor and
Control)
  • Processor 20 MHz 68030 (32 bits processor
    80386)
  • EIA/TIA-232 console port for local system access
    using a console terminal
  • EIA/TIA-232 auxiliary port for remote system
    access using a modem
  • Ethernet

5
Cisco 2500 Router Series Hardware (Models)
The Cisco 2500 series routers provide a variety
of models designed for branch office and remote
site environments. These routers are typically
fixed configuration with at least two of the
following interfaces
  • Ethernet (AUI)
  • 10BaseT Ethernet hub
  • Token ring
  • Synchronous serial
  • Asynchronous serial
  • ISDN BRI

6
Software Configuration of Cisco Router
  • IOS 11.1 - 12.2

Cisco IOS Fundamental
  • Cisco IOS software provides a wide range of
    functionality from basic connectivity,
    security, and network management to technically
    advanced services that enable businesses to
    deploy applications such as real-time trading,
    interactive support, on-demand media, and
    unified messaging.
  • Evolution first-generation networking devices
    could only store and forward data packets , to
    today, Cisco IOS software can recognize,
    classify, and prioritize network traffic,
    optimize routing, support voice and video
    applications etc.

8
Cisco IOS Multiple Protocols Support
  • IP
  • Internetwork Packet Exchange (IPX)
  • AppleTalk
  • DECnet
  • Systems Network Architecture (SNA)

9
Cisco IOS Command-line Interface (CLI)
  • Command-line interface
  • Interface that allows the user to interact with
    the operating system by entering commands and
    optional arguments.
  • Prompt gt or .
  • Learn how to use tab and ?

10
Cisco 2522/2524 IOS Version (11.1 and 12.2)
  • IP Routing
  • IP Routing Plus
  • IP/IPX with IBM base functionality and APPN
  • Desktop (IP/IPX/AppleTalk/DEC)
  • Desktop (IP/IPX/AppleTalk/DEC) Plus
  • Enterprise
  • Enterprise Plus
  • Enterprise/APPN/Plus
  • Mission-specific Cisco 2500 series
    application-specific software

Connecting to Cisco Router
  • Peripheral and Related Network Devices

12
Connections of Cisco Router
  • Ethernet ports and cables (RJ45)
  • Switches
  • Catalyst 1900 (VLAN)
  • Catalyst 5000
  • Hub
  • Serial ports (V.35) and cables
  • Front panels
  • Console

13
Cisco 2524 Back Panel
14
Catalyst 1900 Switch
  • VLAN set up on Catalyst 1900

An Example of Network Connection
18
Private IP Addresses
  • There are three IP network addresses reserved for
    private networks. The addresses are
  • 10.0.0.0/8
  • 172.16.0.0/12
  • 192.168.0.0/16
  • (RFC 1918)

19
Cisco Router Configuration Basis
  • Loop back address (127.0.0.1)
  • Interface IP address
  • Connect to Cisco router (telnet, console, remote
    access through modem)
  • Unprivileged mode (gt) privileged mode ()
  • Use tab and ?

20
Cisco Router Configuration Basis
  • TFTP server transfer config file (through
    Ethernet connection)
  • Diagnose tools
  • Connection ping, traceroute
  • Routing table
  • R1show interfaces r1show ip
    protocols r1show ip route r1show ip arp
  • .

21
Static Routes Configuration Example
  • r1configr1(config)ip route 10.4.0.0
    255.255.0.0 10.3.1.2
  • r1(config)ip route 10.1.1.1 255.255.0.0
    10.1.1.2 r1(config)ctrl-zr1show ip route

Give static routes configuration for following
network
10.1.1.1/16
10.1.1.2/16
10.4.1.1/16
10.4.1.2/16
r1
r2
10.3.1.2/16

  • RTA network 203.250.0.0 0.0.255.255 area 0.0.0.0

24
Save Configuration File
  • TFTP Startup Running

25
Clear Previous Routing Configuration
