实验1：
配置BGP命令
先在OSPF中的AS配置
[R7]ospf 1
[R7-ospf-1]area 0
[R7-ospf-1-area-0.0.0.0]network 10.0.24.0 0.0.0.255
[R7-ospf-1-area-0.0.0.0]network 7.7.7.7 0.0.0.0
配置BGP：
[R1]bgp 100 ——#创建bgp编号为100 (也就是AS100)
[R1-bgp]router-id 1.1.1.1 ——#配置BGP的Router ID
[R1-bgpl peer 2.2.2.2 as-number 100 ——#指定对等体的回环网口IP地址及其所属的AS编号
[R1-bgp]peer 2.2.2.2 connect-interface LoopBack0 ——#更新发送bgp报文的接口为Loopback0接口
[R1-bgp] peer 3.3.3.3 as-number 100
[R1-bgp]peer 3.3.3.3 connect-interface LoopBack0
[R3-bgp]peer 2.2.2.2 next-hop-local——#ASBR从ebgp邻居学习到的路由传递给ibgp邻居时,修改该命令
[R3-bgp]peer 7.7.7.7 ebgp-max-hop 2——#两个AS之间用回环网口建的邻居要将它们的邻居的最大跳数改为2,默认的是1 (因为不是直连而是用Loopbacko接口,需要经过2个路由,而默认EBGP传递时TTL值为1)
[R3-bgp]network 1.1.1.1 255.255.255.255 ——#宣告指定的IGP、静态、默认路由进BGP进程
中间区域AS200：OSPF
左边区域AS100：动态路由RIP
右边区域AS300：动态路由RIP
