动态路由-BGP的基础配置

  
    
  
    
 AR6-1:
    
 #1、添加ip地址
    
 interface GigabitEthernet0/0/0
    
  ip address 1.1.1.1 255.255.255.0 
    
 #
    
 #2、配置BGP对等体
    
 bgp 100    //  配置bgp的AS号为100
    
  peer 1.1.1.2 as-number 200     //配置对等体ip地址1.1.1.2进入到bgp 200
    
  #
    
  
    
  
    
  
    
  
    
  
    
 AR7-1:
    
 #1、添加ip地址

 interface GigabitEthernet0/0/1
    
  ip address 2.2.2.1 255.255.255.0 
    
 #
    
 #添加环回地址
    
 interface LoopBack0
    
  ip address 4.4.4.4 255.255.255.0 
    
 #
    
 #宣告ip地址和环回地址

 #
    
 #
    
 bgp 200    //进入bgp,进入指定的AS号
    
  router-id 4.4.4.4    //添加路由ID
    
  peer 1.1.1.1 as-number 100 //配置对等体
    
  peer 5.5.5.5 as-number 200 //配置对等体
    
  peer 5.5.5.5 connect-interface LoopBack0    //指定用loopback 0
