实验拓扑

在这里插入图片描述

实验需求解法

1.如图所示配置所有路由器接口IP地址

R1:
interface GigabitEthernet0/0/0
ip address 10.0.123.1 255.255.255.0
#
R2:
interface GigabitEthernet0/0/0
ip address 10.0.123.2 255.255.255.0
interface GigabitEthernet0/0/1
ip address 10.0.24.2 255.255.255.0
#
R3:
interface GigabitEthernet0/0/0
ip address 10.0.123.3 255.255.255.0
interface Serial1/0/0
ip address 10.0.34.3 255.255.255.0
#
R4:
interface GigabitEthernet0/0/0
ip address 10.0.24.4 255.255.255.0
interface Serial1/0/0
ip address 10.0.34.4 255.255.255.0
interface GigabitEthernet0/0/1
ip address 10.0.45.4 255.255.255.0
#
R5:
interface GigabitEthernet0/0/0
ip address 10.0.45.5 255.255.255.0
interface LoopBack0
ip address 10.0.5.5 255.255.255.255

2.运行IS-IS,进程号1

R1:
isis 1
is-level level-1
network-entity 49.0123.0000.0000.0001.00
is-name R1
interface GigabitEthernet0/0/0
isis enable 1
#
R2
isis 1
network-entity 49.0123.0000.0000.0002.00
is-name R2
interface GigabitEthernet0/0/0
isis enable 1
interface GigabitEthernet0/0/1
isis enable 1
#
R3:
isis 1
network-entity 49.0123.0000.0000.0003.00
is-name R3
interface GigabitEthernet0/0/0
isis enable 1
interface Serial1/0/0
isis enable 1
#
R4:
isis 1
is-level level-2
network-entity 49.0004.0000.0000.0004.00
is-name R4
interface GigabitEthernet0/0/0
isis enable 1
interface GigabitEthernet0/0/1
isis enable 1
interface Serial1/0/0
isis enable 1
#
R5:
isis 1
is-level level-2
network-entity 49.0005.0000.0000.0005.00
is-name R5
interface GigabitEthernet0/0/0
isis enable 1
interface LoopBack0 
isis enable 1

3.IS-IS优化

R1:
interface GigabitEthernet0/0/0
isis dis-priority 120
  • 3.2 在R2/3上修改circuit-level,使得R2/3向R1只发送Level-1的IIH,向R4只发送Level-2的IIH。(IIH:ISIS Hello查看R2/3的ISIS邻居,确认R2与R3只有L1的邻居关系
R2:
interface GigabitEthernet0/0/0
isis circuit-level level-1
interface GigabitEthernet0/0/1
isis circuit-level level-2
#
R3:
interface GigabitEthernet0/0/0
isis circuit-level level-1
interface Serial1/0/0
isis circuit-level level-2
R4interface GigabitEthernet0/0/1
isis circuit-type p2p
#
R5interface GigabitEthernet0/0/0
isis circuit-type p2p

4.路径优化

R2/3:
isis 1
import-route isis level-2 into level-1
[R1]dis ip routing-table 10.0.5.5

在这里插入图片描述

R2/3:
isis 1
auto-cost enable
[R1]dis ip routing-table 10.0.5.5

在这里插入图片描述
