实验00 Basic BGP Configuration

• R2 是先no 掉 ipv4，然后进去到 address-falimy 单独 Activate

#R1
router bgp 65100
 neighbor 10.12.1.2 remote-as 65200
 neighbor 10.12.1.2 password CISCO
 neighbor 10.12.1.2 timers 10 40
#R2
router bgp 65200
 bgp log-neighbor-changes
 no bgp default ipv4-unicast
 neighbor 10.12.1.1 remote-as 65100
 neighbor 10.12.1.1 password CISCO
 neighbor 10.12.1.1 timers 20 100
 address-family ipv4
  neighbor 10.12.1.1 activate
 exit-address-family

• verification
  • show ip bgp ipv4 unicast summary
  • show ip bgp ipv4 unicast neighbors 10.12.1.2
  • show ip bgp summary
  • 查看配置时的参数，协商后真正使用的参数，谁是本地179
  • show tcp brief

实验01 Prefix Advertisement

1. 在R1上配置EIGRP，Static，OSPF，查看路由表，确认获取到路由
2. 配置 BGP
