1、拓扑图
配置RIP和OSPF，为了让PC1和PC2实现通信。
2、实验配置
（1）配置IP地址
配置PC的IP地址和网关
（2）配置路由器IP地址
配置AR1路由器对应接口的IP地址
<Huawei>sys
[Huawei]sysname AR1
[AR1]undo info-center enable
[AR1]interface g0/0/0
[AR1-GigabitEthernet0/0/0]ip add 100.1.1.254 24
[AR1-GigabitEthernet0/0/0]int g0/0/1
[AR1-GigabitEthernet0/0/1]ip add 12.1.1.1 30
[AR1-GigabitEthernet0/0/1]int g0/0/2
[AR1-GigabitEthernet0/0/2]ip add 13.1.1.1 30
[AR1-GigabitEthernet0/0/2]q
配置AR2路由器对应接口的IP地址
<Huawei>sys
[Huawei]sysname AR2
[AR2]undo info-center enable
[AR2]int g0/0/1
[AR2-GigabitEthernet0/0/1]ip add 23.1.1.1 30
[AR2-GigabitEthernet0/0/1]int g0/0/0
[AR2-GigabitEthernet0/0/0]ip add 12.1.1.2 30
[AR2-GigabitEthernet0/0/0]q
配置AR3路由器对应接口的IP地址
<Huawei>sys
[Huawei]sysname AR3
[AR3]int g0/0/0
[AR3-GigabitEthernet0/0/0]ip add 13.1.1.2 30
[AR3-GigabitEthernet0/0/0]q
[AR3]undo info-center enable
[AR3]int g0/0/1
[AR3-GigabitEthernet0/0/1]ip add 23.1.1.2 30
[AR3-GigabitEthernet0/0/1]int g0/0/2
[AR3-GigabitEthernet0/0/2]ip add 34.1.1.1 30
[AR3-GigabitEthernet0/0/2]q
配置AR4路由器对应接口的IP地址
<Huawei>sys
[Huawei]sysname AR4
[AR4]undo info-center enable
[AR4]int g0/0/0
[AR4-GigabitEthernet0/0/0]ip add 34.1.1.2 30
[AR4-GigabitEthernet0/0/0]int g0/0/1
[AR4-GigabitEthernet0/0/1]ip add 45.1.1.1 30
[AR4-GigabitEthernet0/0/1]q
配置AR5路由器对应接口的IP地址
<Huawei>sys
[Huawei]sysname AR5
[AR5]undo info-center enable
[AR5]int g0/0/0
[AR5-GigabitEthernet0/0/0]ip add 45.1.1.2 30
[AR5-GigabitEthernet0/0/0]int g0/0/1
[AR5-GigabitEthernet0/0/1]ip add 200.1.1.254 24
[AR5-GigabitEthernet0/0/1]q
[AR5]dis current-configuration 经过以上配置之后，一定要先检查一下IP地址是否配置正确，再进行下一步操作。
[AR5]display ip interface brief 或者ping 一下直连。
（3）配置AS 100内部的路由信息
在AR1、AR2、AR3中运行RIP协议。
在AR1中进行配置
<AR1>sys
[AR1]rip ?
INTEGER<1-65535> Process ID
mib-binding Mib-Binding a process
vpn-instance VPN instance
<cr> Please press ENTER to execute command
[AR1]rip 1
将AR1的三个网段都宣告到RIP 1中
[AR1-rip-1]
[AR1-rip-1]network 100.1.1.0
Error: The network address is invalid, and the specified address must be major-n
et address without any subnets.
上述命令出错，默认是RIPv1
修改为RIPv2
[AR1-rip-1]version 2
[AR1-rip-1]network 100.1.1.0
Error: The network address is invalid, and the specified address must be major-n
et address without any subnets.
修改版本之后依旧报错。因为只能宣告主类网络。对外宣告路由时携带子网掩码。
[AR1-rip-1]net
[AR1-rip-1]network 100.0.0.0
[AR1-rip-1]net
[AR1-rip-1]network 12.0.0.0
[AR1-rip-1]net
[AR1-rip-1]network 13.0.0.0
[AR1-rip-1]q
在AR2中进行配置
<AR2>sys
[AR2]rip 1
[AR2-rip-1]version 2
[AR2-rip-1]net
[AR2-rip-1]network 12.0.0.0
[AR2-rip-1]net
[AR2-rip-1]network 23.0.0.0
[AR2-rip-1]q
在AR3中进行配置
<AR3>sys
[AR3]rip 1
[AR3-rip-1]version 2
[AR3-rip-1]net
[AR3-rip-1]network 23.0.0.0
[AR3-rip-1]net
[AR3-rip-1]network 13.0.0.0
[AR3-rip-1]q
[AR3]dis ip routing-table

[AR3]上述配置是RIP，也可以配置成OSPF
（4）配置BGP
在AR3和AR4之间运行同一个EBGP。
在AR3中配置
<AR3>sys
Enter system view, return user view with Ctrl+Z.
[AR3]bgp 100
[AR3-bgp]peer 34.1.1.2 as-number 200
在AR4中配置
<AR4>sys
[AR4]bgp 200
[AR4-bgp]peer 34.1.1.1 as-number 100
[AR4-bgp]peer 45.1.1.2 as-number 200
在AR5中配置
<AR5>
<AR5>sys
[AR5]bgp 200
[AR5-bgp]peer 45.1.1.1 as-number 200
[AR5-bgp]q
查看AR4中的配置信息
[AR4]dis bgp peer

在AR5中宣告路由
宣告IPv4的单播路由
[AR5]bgp 200
[AR5-bgp]ipv4-family unicast
[AR5-bgp-af-ipv4]network 200.1.1.0 24
再次查看AR4中的路由信息，已经学到200.1.1.0网段的地址

AR5\]dis bgp routing-table 显示AR5已经学到100.1.1.0网段的信息，但是没有加入路由表中，因为显示的bgp路由表下一跳是 34.1.1.1，而AR5中没有这条路由，不可达。 [AR5]dis bgp routing-table BGP Local router ID is 200.1.1.254 Status codes: * - valid, > - best, d - damped, h - history, i - internal, s - suppressed, S - Stale Origin : i - IGP, e - EGP, ? - incomplete Total Number of Routes: 5 Network NextHop MED LocPrf PrefVal Path/Ogn i 12.1.1.0/30 34.1.1.1 1 100 0 100? i 13.1.1.0/30 34.1.1.1 0 100 0 100? i 23.1.1.0/30 34.1.1.1 0 100 0 100? i 100.1.1.0/24 34.1.1.1 1 100 0 100? *> 200.1.1.0 0.0.0.0 0 0 i [AR5] 而AR5中没有这条路由，不可达，解决方法有两种，一种是直接写静态路由。 [AR5]ip route-static 34.1.1.0 30 45.1.1.1 [AR5]dis ip routing-table Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: Public Destinations : 15 Routes : 15 Destination/Mask Proto Pre Cost Flags NextHop Interface 12.1.1.0/30 IBGP 255 1 RD 34.1.1.1 GigabitEthernet 0/0/0 13.1.1.0/30 IBGP 255 0 RD 34.1.1.1 GigabitEthernet 0/0/0 23.1.1.0/30 IBGP 255 0 RD 34.1.1.1 GigabitEthernet 0/0/0 34.1.1.0/30 Static 60 0 RD 45.1.1.1 GigabitEthernet 0/0/0 45.1.1.0/30 Direct 0 0 D 45.1.1.2 GigabitEthernet 0/0/0 45.1.1.2/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/0 45.1.1.3/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/0 100.1.1.0/24 IBGP 255 1 RD 34.1.1.1 GigabitEthernet 0/0/0 127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0 127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0 127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 200.1.1.0/24 Direct 0 0 D 200.1.1.254 GigabitEthernet 0/0/1 200.1.1.254/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/1 200.1.1.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/1 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 [AR5] 而AR5中没有这条路由，不可达，解决方法有两种，第二种方案在AR4上配置。有点难。 在AR4中配置 [AR4]bgp 200 [AR4-bgp]peer 45.1.1.2 next-hop-local 进行上述配置之后AR5的路由表信息 [AR5]dis ip routing-table Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: Public Destinations : 14 Routes : 14 Destination/Mask Proto Pre Cost Flags NextHop Interface 12.1.1.0/30 IBGP 255 1 RD 45.1.1.1 GigabitEthernet 0/0/0 13.1.1.0/30 IBGP 255 0 RD 45.1.1.1 GigabitEthernet 0/0/0 23.1.1.0/30 IBGP 255 0 RD 45.1.1.1 GigabitEthernet 0/0/0 45.1.1.0/30 Direct 0 0 D 45.1.1.2 GigabitEthernet 0/0/0 45.1.1.2/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/0 45.1.1.3/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/0 100.1.1.0/24 IBGP 255 1 RD 45.1.1.1 GigabitEthernet 0/0/0 127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0 127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0 127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 200.1.1.0/24 Direct 0 0 D 200.1.1.254 GigabitEthernet 0/0/1 200.1.1.254/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/1 200.1.1.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/1 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 [AR5] [AR5]dis bgp routing-table BGP Local router ID is 200.1.1.254 Status codes: * - valid, > - best, d - damped, h - history, i - internal, s - suppressed, S - Stale Origin : i - IGP, e - EGP, ? - incomplete Total Number of Routes: 5 Network NextHop MED LocPrf PrefVal Path/Ogn *>i 12.1.1.0/30 45.1.1.1 1 100 0 100? *>i 13.1.1.0/30 45.1.1.1 0 100 0 100? *>i 23.1.1.0/30 45.1.1.1 0 100 0 100? *>i 100.1.1.0/24 45.1.1.1 1 100 0 100? *> 200.1.1.0 0.0.0.0 0 0 i [AR5] #### （6）实验结果验证 PC>ping 200.1.1.1 Ping 200.1.1.1: 32 data bytes, Press Ctrl_C to break Request timeout!
