1.     IP 地址的规划

路由器号
端口号及IP

 

R1
S1/0 :172.16.61.1

S2/0 :172.16.41.1

F0/0 :172.16.12.1

 

R2

 
F0/0 :172.16.12.2

S1/0 :172.16.23.2

Loopback:172.16.22.2

 

R3
S0/0 :172.16.23.3

S1/0 :172.16.35.3

R4
S0/1 :172.16.41.4

R5
S0/0 :172.16.35.5

R6
S0/0 :172.16.61.6

2.     区域说明

范围
区域号
区域类型

R6(S0/0) —— R1(S1/0)
30
totally stubby

R1(F0/0) —— R2(F0/0)
0
骨干区域

R4(S0/1) —— R1(S2/0)
10
stub

R2(S1/0) —— R3(S0/0)
20
nssa

R2 (Loopback)
40
标准区域

注: R3(S1/0) ——R5(S0/0)是RIP AS
