Cisco IOS router > Normal operation
1.3 Command Modes命令模式。
User EXEC Router> user access
Privileged EXEC Router# System adminstration
Configuration mode Router(config)# Modify configuration
Setup Prompted dialog Create the initial
configuration
二 配置前的準備工作
2.1 用終端或仿真終端接入CONSOLE口 。
終端或仿真終端配置信息如下:
9600 baud 8 data bits no parity 2 stop bits (9600,8/N/2)
2.2 用TELNET命令在網上進行設置。
系統管理員可在網上用telnet address命令進行遠程配置。
三 配置方法
3.1 Auto install
3.2 setup
3.3 config 命令行設置-
四 配置IP地址
4. 1採用 (3.1 /3.2) 方法進行配置。
4.2 config命令行方式進行設置
4.2.1 首先啓動ROUTER 進入router > 模式。
鍵入Enable 進入router # 模式
然後鍵入config 進入router(config)# 模式
4.2.2 選擇要配置的路由器端口
Router(config) # interface端口號
進入端口設置狀態 Router(config-if)
此時用命令IP address<掩碼>
設定路由器端口IP地址
五 配置ip路由協議 (RIP ,OSPF ,BGP ,STATICS)
在globle模式下配置 例圖見附圖。
5. 1靜態路由
IP route 目的網絡地址 子網掩碼 端口號
例:在RA1上配RA2的路由
IP route 10.0.210.4 255.255.255.252 E0
5.2 RIP2設置
以路器A1爲例進行如下設置
router rip ;enable rip
version 2 ;選擇版本2
network 10.86.16.0 ;相關子網地址
network 10.85.1.4
network 10.85.1.8
5.3 OSPF設置
以路由器D爲例進行如下配置
router ospf 200 ;enable ospf 進程號爲200
redistribute bgp 200 subnets ;
network 10.0.210.4 0.0.0.3 area 1 ; 相關子網地址及區域號
network 10.185.1.16 0.0.0.3 area 1
5.4 BGP設置
以路由器A2和D爲例
A2:
router bgp 100 ;enable bgp 設置自治域號
network 10.0.210.4 mask 255.255.255.252 ;相關子網地址及子
網掩碼
network 10.80.0.0 mask 255.240.0.0 ; 這些地址由bgp發到鄰
居路由器
redistribute rip
neighbor 10.0.210.6 remote-as 200 ;設置遠程相連自治域邊
界路由器端口
D2:
router bgp 200
network 10.0.210.4 mask 255.255.255.252
network 10.0.32.0 mask 255.255.240.0
network 10.185.1.16 mask 255.255.255.252
network 10.0.1.0 mask 255.255.255.252
neighbor 10.0.210.5 remote-as 100
六 radius認證的設置
6.1 radius的簡述
RADIUS的全稱爲(Remote Access Dail-In User Service),它是對遠程撥號用戶訪問進行認證的一種協議。主要進行Authentication Authorization Accounting (AAA) 三方面的工作。
6.2 radius的配置
具體配置如下:
aaa new-mode ;enable radius
radius-server host ;指明radius server在網
上的地址
radius-server key;建立一個網上傳輸密
aaa authentication login default radius local ;進行login認證,若radius
server未找到從本地數據庫內查找
aaa authentication ppp default radius local
aaa authorization network radius local ;授權檢測
aaa accounting network start-stop radius ;計帳檢測
七 路由器軟件升級方法
7.1 改變操作環境
在global config mode設置: config -reg 0x2101
reload 進入Boot Rom 模式:router(boot)>
7.2 運行tftp server
在網上運行tftp server,使升級文件可以傳輸。
7.3 升級版本
命令如下:
copy tftp flash ;將tftp server上的文件傳入路由器的flash memoy中
copy flash tftp ; j將flash中的文件備份到tftp server中
八 配置路由器的一些注意事項
8.1撥號用戶的配置。
cisco 2509/2511的異步串行通訊口在配置modem時,modem需設置成自動應答方式。具體方法如下:
用超級終端進入modem AT 命令方式,鍵入ats0=1 設置自動應答方式,然後鍵入at&w 將設置寫入寄存器。
8.2 RIP & BGP的設置
當一個運行RIP路由協議的子網,做爲一個自治域,用BGP協議接入另一
自治域時。此子網內所有路由器需添加參數: ip classless 。同時在
與邊界路由器直接相連的路由器上需添加一個缺省網關。
設置如下:
ip 0.0.0.0 0.0.0.0 邊界路由器地址。
8.3 v.35電纜直連的設置
在相關的端口上設置時鐘速率:clock rate < speed> .
8.4 loopback端口的設置
loopback端口是一個虛擬端口,端口狀態始終處於UP。通過它可以使由BGP相連的AS之間始終保持連繫,不會由於邊界路由器端口狀態的改變而發生變化。其具體配置如下:
interface loopback
九常用的路由器命令 (見附錄)
十 問與答
10.1如何檢測網絡是否通暢?
A:在網絡主機上採用命令ping來逐端檢測網端。
10.2如何查看路由器配置信息?
A:在EXEC模式下用show config命令。
10.3如何查看路由器路由信息?
A:在EXEC模式下用show ip route 命令。
10.4如何查看路由器端口信息?
A:在EXEX模式下用show int <端口號> 命令。
10.5爲什麼端口協議已經配置,狀態仍然是down?
A:在CONFIG模式下,選擇該端口,執行no shutdwon命令。
10.6 config模式有幾種狀態,對應那些操作?
A:config模式有以下幾種狀態:
• globle config 全局配置操作 exec模式鍵入config t
• interface config 端口配置操作 config模式鍵入int <端口號>
• line config 線路配置操作 config模式鍵入line <線路號>
• router config 路由配置操作 config模式鍵入router<路由
協議>
