1. 配置IBGP 和EBGP
2. 分配AS
   实验步骤：
3. 为每一台路由器配置虚拟地址以及IP地址
   例：Interface GigabitEthernet 0/0/0
   Ip address 192.168.10.1 255.255.255.0
   Interface lookback 0
   Ip address 10.10.10.1 255.255.255.0
4. AR2至AR5 配置ospf
   例： AR2：OSPF 1 router-id 2.2.2.2
   Area 0
   Network 192.168.20.0 0.0.0.255
   Network 10.10.2.2 0.0.0.0
   AR3:ospf 1 router-id 3.3.3.3
   Area 0
   Network 192.168.20.0 0.0.0.255
   Network 192.168.30.0 0.0.0.255
   Network 10.10.3.3 0.0.0.0
   3.AR1 的AS 设置为100
   AR2至AR5设置大AS号为200
   AR6设置为600
   AR2 和AR3设置为小AS 64523
   AR4 和AR5 设置为小AS 64545
   4.配置命令：
   R1:
   undo terminal monitor
   system-view
   sysname R1
   interface loopback 0
   ip address 10.10.1.1 32
   interface gigabitethernet 0/0/0
   ip address 192.168.10.1 24
   quit
   bgp 100
   router 1.1.1.1
   peer 192.168.10.2 as-number 200
   network 10.10.1.1 255.255.255.255
   quit
