HCIP第五天

 

 1.划分level

ISIS的骨干区域为逻辑骨干---所有连续的L2和L1-2路由器的集合构成了ISIS的逻辑骨干区域一个区域内至少有一台设备属于逻辑骨干，否则该区域将无法访问其他区域；判断出R7为L2所以R8和R6为L12，R2 R3 R4 R6 R7 R8为主干路，也可以将R8为L1。

2.配置

R6基本配置
[r6]interface g0/0/1
[r6-GigabitEthernet0/0/1]ip address 46.1.1.2 24
[r6]interface g0/0/0
[r6-GigabitEthernet0/0/0]ip address 56.1.1.2 24
[r6]interface g0/0/2
[r6-GigabitEthernet0/0/2]ip address 67.1.1.2 24	
[r6]interface LoopBack  0
[r6-LoopBack0]ip address 6.6.6.6 32
[r6]isis 1 
[r6-isis-1]network-entity 49.0001.6666.6666.6666.00
[r6]interface g0/0/0
[r6-GigabitEthernet0/0/0]isis enable 1
[r6]interface g0/0/1	
[r6-GigabitEthernet0/0/1]isis enable 1
[r6]interface g0/0/2	
[r6-GigabitEthernet0/0/2]isis enable  1	
[r6]interface LoopBack  0
[r6-LoopBack0]isis enable  1

 3.全网可达

 4.使路由表精简化

[r1]isis 1
[r1-isis-1]is-level level-1

 5.R5访问R1走R6

使用路由泄露在R6上配置
[r6]acl 2000	
[r6-acl-basic-2000]rule permit source 1.1.1.1 0.0.0.0	
[r6]isis 1
[r6-isis-1]import-route isis level-2 into level-1 filter-policy 2000
