第一步：IP 地址规划

基于 192.168.1.0/24 进行子网划分。

1. Area 0 网络 (LSW1 连接的网络): 192.168.1.0/27
  可用地址范围: 192.168.1.1 - 192.168.1.30
  掩码: 255.255.255.224 (/27)
  AR1 GE 0/0/0: 192.168.1.10/27
  AR2 GE 0/0/0: 192.168.1.20/27
  AR3 GE 0/0/0: 192.168.1.30/27
  此网段广播地址: 192.168.1.31
2. Area 1 网络 (AR3 - AR4): 192.168.1.32/30
  可用地址范围: 192.168.1.33 - 192.168.1.34
  掩码: 255.255.255.252 (/30)
  AR3 GE 0/0/1: 192.168.1.33/30
  AR4 GE 0/0/0: 192.168.1.34/30
3. Area 1 网络 (AR4 - AR5): 192.168.1.36/30
  可用地址范围: 192.168.1.37 - 192.168.1.38
  掩码: 255.255.255.252 (/30)
  AR4 GE 0/0/1: 192.168.1.37/30
  AR5 GE 0/0/0: 192.168.1.38/30
4. 环回接口 (Loopback)
  AR1 Loopback 0: 192.168.1.1/32
  AR2 Loopback 0: 192.168.1.2/32
  AR5 Loopback 0: 192.168.1.5/32

第二部基础ip配置

ar1

sysname AR1
interface GigabitEthernet 0/0/0
 ip address 192.168.1.10 255.255.255.224
 quit
interface LoopBack 0
 ip address 192.168.1.1 255.255.255.255
 quit

ar2

sysname AR2
interface GigabitEthernet 0/0/0
 ip address 192.168.1.20 255.255.255.224
 quit
interface LoopBack 0
 ip address 192.168.1.2 255.255.255.255
 quit

ar3

sysname AR3
interface GigabitEthernet 0/0/0
 ip address 192.168.1.30 255.255.255.224
 quit
interface GigabitEthernet 0/0/1
 ip address 192.168.1.33 255.255.255.252
 quit

ar4

 ip address 192.168.1.38 255.255.255.252
 quit
interface LoopBack 0
 ip address 192.168.1.5 255.255.255.255
 quit

lsw1

sysname LSW1
vlan batch 10
interface GigabitEthernet 0/0/1

 port default vlan 10
 quit
interface GigabitEthernet 0/0/2

 port default vlan 10
 quit
interface GigabitEthernet 0/0/3
 port link-type access
 port default vlan 10
 quit

第三步：OSPF 基础配置

ar1

ospf 1 router-id 1.1.1.1
 area 0.0.0.0
  network 192.168.1.10 0.0.0.0
  network 192.168.1.1 0.0.0.0
 quit
interface GigabitEthernet 0/0/0
 ospf dr-priority 100
 quit

ar2

ospf 1 router-id 2.2.2.2
 area 0.0.0.0
  network 192.168.1.20 0.0.0.0
  network 192.168.1.2 0.0.0.0
 quit
interface GigabitEthernet 0/0/0
 ospf dr-priority 50
 quit
