生活随笔收集整理的這篇文章主要介紹了路由器交换与配置综合实验（二）外网小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

實驗拓撲圖

外網配置

配置主機

先認證再捆綁

使用CHAP認證進行

RT1主驗證（采用簡單的接口驗證

[RT1]local-user rt2 class network New local user added.[RT1-luser-network-rt2]password simple rt2[RT1-luser-network-rt2]service-type ppp [RT1-luser-network-rt2]quit[RT1]inter s1/0 [RT1-Serial1/0]ppp authentication-mode chap[RT1-Serial1/0]inter s2/0 [RT1-Serial2/0]ppp authentication-mode chap

）

RT1配置完成后，RT2馬上開啟認證

[RT2]inter s1/0[RT2-Serial1/0]ppp chap password simple rt2 [RT2-Serial1/0]dis inter s1/0 Serial1/0 Current state: UP Line protocol state: UP Description: Serial1/0 Interface Bandwidth: 64 kbps Maximum transmission unit: 1500 Hold timer: 10 seconds, retry times: 5 Internet protocol processing: Disabled Link layer protocol: PPP LCP: opened Output queue - Urgent queuing: Size/Length/Discards 0/100/0 Output queue - Protocol queuing: Size/Length/Discards 0/500/0 Output queue - FIFO queuing: Size/Length/Discards 0/75/0 Last link flapping: 0 hours 42 minutes 4 seconds Last clearing of counters: Never

此時接口處于open狀態，所以我們需要重啟接口進行驗證

[RT2-Serial1/0]shut[RT2-Serial1/0]undo shut[RT2-Serial1/0]dis inter s1/0 Serial1/0 Current state: UP Line protocol state: UP Description: Serial1/0 Interface Bandwidth: 64 kbps Maximum transmission unit: 1500 Hold timer: 10 seconds, retry times: 5 Internet protocol processing: Disabled Link layer protocol: PPP LCP: opened Output queue - Urgent queuing: Size/Length/Discards 0/100/0 Output queue - Protocol queuing: Size/Length/Discards 0/500/0 Output queue - FIFO queuing: Size/Length/Discards 0/75/0 Last link flapping: 0 hours 0 minutes 34 seconds Last clearing of counters: Never

接口仍處于open狀態則說明驗證成功，進入接口S2/0驗證

[RT2]inter s2/0 [RT2-Serial2/0]ppp chap user rt2 [RT2-Serial2/0]ppp chap password simple rt2 [RT2-Serial2/0]dis inter s2/0 Serial2/0 Current state: UP Line protocol state: UP Description: Serial2/0 Interface Bandwidth: 64 kbps Maximum transmission unit: 1500 Hold timer: 10 seconds, retry times: 5 Internet protocol processing: Disabled Link layer protocol: PPP LCP: opened Output queue - Urgent queuing: Size/Length/Discards 0/100/0 Output queue - Protocol queuing: Size/Length/Discards 0/500/0 Output queue - FIFO queuing: Size/Length/Discards 0/75/0 Last link flapping: 0 hours 54 minutes 43 seconds Last clearing of counters: Never[RT2-Serial2/0]shut [RT2-Serial2/0]%Dec 23 11:57:36:968 2021 RT2 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Serial2/0 changed to down. %Dec 23 11:57:36:968 2021 RT2 IFNET/3/PHY_UPDOWN: Physical state on the interface Serial2/0 changed to down.[RT2-Serial2/0]undo shut [RT2-Serial2/0]%Dec 23 11:57:44:464 2021 RT2 IFNET/3/PHY_UPDOWN: Physical state on the interface Serial2/0 changed to up. %Dec 23 11:57:44:465 2021 RT2 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Serial2/0 changed to up.[RT2-Serial2/0]dis inter s2/0 Serial2/0 Current state: UP Line protocol state: UP Description: Serial2/0 Interface Bandwidth: 64 kbps Maximum transmission unit: 1500 Hold timer: 10 seconds, retry times: 5 Internet protocol processing: Disabled Link layer protocol: PPP LCP: opened Output queue - Urgent queuing: Size/Length/Discards 0/100/0 Output queue - Protocol queuing: Size/Length/Discards 0/500/0 Output queue - FIFO queuing: Size/Length/Discards 0/75/0 Last link flapping: 0 hours 0 minutes 4 seconds Last clearing of counters: Never

驗證結束，下面開始進行捆綁，先建立捆綁組，給捆綁組配置IP地址，再進入接口，把接口加入捆綁組

[RT1]inter mp [RT1]inter MP-group 1 [RT1-MP-group1]ip add 100.0.0.1 24 [RT1-MP-group1]quit [RT1]inter s1/0 [RT1-Serial1/0]ppp mp mp [RT1-Serial1/0]ppp mp MP-group 1 [RT1-Serial1/0]%Dec 23 12:03:58:777 2021 RT1 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Serial1/0 changed to down. %Dec 23 12:04:01:836 2021 RT1 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Serial1/0 changed to up.[RT1-Serial1/0]inter s2/0 [RT1-Serial2/0]ppp mp mp1 [RT1-Serial2/0]%Dec 23 12:04:56:494 2021 RT1 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Serial2/0 changed to down. %Dec 23 12:04:59:536 2021 RT1 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Serial2/0 changed to up.

給RT2的g0/0接口配置ip地址

[RT2]inter g0/0[RT2-GigabitEthernet0/0]ip add 100.0.1.254 24 [RT2-GigabitEthernet0/0]quit

查看RT2路由表是否出現100.0.0以及100.0.1兩個字段

用ospf配置路由

[RT1-ospf-1]ospf [RT1-ospf-1]ar [RT1-ospf-1]area 0 [RT1-ospf-1-area-0.0.0.0]net 100.0.0.0 0.0.0.255 [RT1-ospf-1-area-0.0.0.0]quit [RT1-ospf-1]quit [RT2]ospf [RT2-ospf-1]ar [RT2-ospf-1]area 0 [RT2-ospf-1-area-0.0.0.0]net 100.0.0.0 0.0.0.255 [RT2-ospf-1-area-0.0.0.0]%Dec 23 12:28:22:096 2021 RT2 OSPF/5/OSPF_NBR_CHG: OSPF 1 Neighbor 100.0.0.1(MP-group1) changed from LOADING to FULL.[RT2-ospf-1-area-0.0.0.0]net 100.0.1.0 0.0.0.255 [RT2-ospf-1-area-0.0.0.0]quit [RT2-ospf-1]quit

查看RT2，RT1路由表，RT2直連最優，RT1出現100.0.1字段說明能連通外網主機，并通過ping命令檢查連通性

此時，整個外網均已連通
