BGP相关实验

一、实验要求
二、拓扑搭建及IP地址规划

三、相关配置
IP地址及回环配置

interface GigabitEthernet0/0/0
ip address 12.1.1.1 255.255.255.0
AS2区域内宣告OSPF


ospf 1 router-id 2.2.2.2
area 0.0.0.0
network 2.2.2.2 0.0.0.0
network 172.16.0.0 0.0.255.255
AS1、AS3与AS2建立EBGP关系

测试R1与R8回环是否可互通


R1与R8另外两个环回通过GRE技术来实现互通

interface Tunnel0/0/0
ip address 192.168.3.2 255.255.255.0
tunnel-protocol gre
source 10.1.1.1
destination 10.1.2.1
ip route-static 192.168.2.0 255.255.255.0 Tunnel0/0/0
测试192.168.1.0/24与192.168.2.0/24
