实验拓扑：

实验步骤：

Do the public network part firstIP配置：

r2

[Huawei]sysname r2
[r2]int l0
[r2-LoopBack0]ip add 2.2.2.2 24
[r2-LoopBack0]int g0/0/1
[r2-GigabitEthernet0/0/1]ip ad 23.1.1.1 24

r3

[Huawei]sysname r3
[r3]int l0
[r3-LoopBack0]ip add 3.3.3.3 24
[r3-LoopBack0]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add 23.1.1.2 24
[r3-GigabitEthernet0/0/0]int g0/0/1 
[r3-GigabitEthernet0/0/1]ip add 34.1.1.1 24

r4

[Huawei]sysname r4
[r4]int l0
[r4-LoopBack0]ip add 4.4.4.4 24
[r4-LoopBack0]int g0/0/0
[r4-GigabitEthernet0/0/0]ip add 34.1.1.2 24
[r4-GigabitEthernet0/0/0]int g4/0/0
[r4-GigabitEthernet4/0/0]ip add 47.1.1.1 24

r7

[Huawei]sysname  r7
[r7]int g0/0/0
[r7-GigabitEthernet0/0/0]ip add 47.1.1.2 24

The focus of the public network part：

Start the public network partigp

Notice the announcement47网段,使得 2、3知晓

将4连7的接口4/0/0Tune to silent interface

[r4-ospf-1]silent-interface g4/0/0

先将opsf中的4、7Authentication encryption is performed after the interface between them is silent,使得4、7will not exist in betweenospf

[r4-GigabitEthernet4/0/0]ospf authentication-mode md5 1 cipher 123456

7Have to write the default to point to the operator（公网）

[r7]ip route-static 0.0.0.0 0 47.1.1.1 

ISP内部的IGP的配置——这里使用OSPF

mpls协议：

 mpls vpn部分

创建vpn空间  

vpnSpace configuration commands：
[r2]ip vpn-instance b1
[r2-vpn-instance-b1]route-distinguisher 1:1
[r2-vpn-instance-b1-af-ipv4]vpn-target 1:1
[r2-vpn-instance-b1-af-ipv4]q
[r2-vpn-instance-b1]q
[r2]ip vpn-instance a1
[r2-vpn-instance-a1]rout
[r2-vpn-instance-a1]route-distinguisher  2:2
[r2-vpn-instance-a1-af-ipv4]vpn-target 2:2

查看当前配置：
[r2]display current-configuration 

r2 r4Separate two spaces for associating two users

Space interface connection：

 bgp关系建立

r2 r4建邻

[r2]bgp 1
[r2-bgp]route-select 
[r2-bgp]router-id 2.2.2.2
[r2-bgp]peer 4.4.4.4 as-number 1
[r2-bgp]peer 4.4.4.4 connect-interface l0
[r2-bgp]ipv4-family vpnv4                         //Used to transmit private routes 
[r2-bgp-af-vpnv4]peer 4.4.4.4 enable     // 建立传输vpn路由

r4

View neighbor relationship establishment

<r3>display  mpls ldp peer 

 The public network environment was successfully established！！！

Perform customer configuration

r6

[Huawei]sysname r6
[r6]int l0
[r6-LoopBack0]ip add 192.168.1.1 24
[r6-LoopBack0]in  g0/0/2
[r6-GigabitEthernet0/0/2]ip add 192.168.2.1 24

[r6]rip 1                //rip协议
[r6-rip-1]ver 2
[r6-rip-1]network 192.168.1.0   宣告网段
[r6-rip-1]network 192.168.2.0

r2：

[r2]rip 1 vpn-instance a1
[r2-rip-1]ver 2
[r2-rip-1]network 192.168.2.0

r2和r6  rip协议启动

接下来该r4 r7启动ospf协议

r7

[r7]int g0/0/02
[r7-GigabitEthernet0/0/2]ip add 192.168.3.2 24
[r7-GigabitEthernet0/0/2]int l0
[r7-LoopBack0]ip add 192.168.4.2 24
[r7-LoopBack0]q
[r7]ospf 1 router-id 7.7.7.7
[r7-ospf-1]area 0
[r7-ospf-1-area-0.0.0.0]network 172.168.3.2 0.0.0.0  //Announce private network segment and loopback
[r7-ospf-1-area-0.0.0.0]network 192.168.4.2 0.0.0.0

r4：

[r4]ospf 2 vpn-instance a2
[r4-ospf-2]area 0
[r4-ospf-2-area-0.0.0.0]network 192.168.3.1 0.0.0.0

r4  r7生成ospf邻接关系

 Next is a two-way repost

r2

[r2]rip 1 vpn-instance  a1 
[r2-rip-1]import-route bgp 
[r2-rip-1]bgp 1
[r2-bgp]ipv4-family vpn-instance a1
[r2-bgp-a1]import-route rip 1   // will be in spacevpnroute to getbgp里

r4

[r4]bgp 1
[r4-bgp]ipv4-family vpn-instance a2
[r4-bgp-a2]import-route ospf 2
[r4-bgp-a2]q 
[r4-bgp]q
[r4]ospf 2 vpn-instance  a2 
[r4-ospf-2]import-route bgp

静态路由配置

r1

[r1]ip route-static 192.168.3.0 24 192.168.2.2
[r1]ip route-static 192.168.4.0 24 192.168.2.2

r2Write static routes to the space

[r2]ip route-static vpn-instance b1 192.168.1.0 24 192.168.2.1

[r2]bgp 1
[r2-bgp]ipv4-family vpn-instance b1
[r2-bgp-b1]import-route direct 
[r2-bgp-b1]import-route static 

[r4]bgp 1
[r4-bgp]ipv4-family vpn-instance b2
[r4-bgp-b2]import-route  static 
[r4-bgp-b2]import-route direct

r2  r4Unreachable routes learned separately

 r2  r4上vpn学到的路由

 r5：静态路由

[r5]int g0/0/0
[r5-GigabitEthernet0/0/0]ip add 192.168.3.2 24
[r5-GigabitEthernet0/0/0]int l0
[r5-LoopBack0]ip add 192.168.4.1 24
[r5-LoopBack0]q
[r5]ip route-static 192.168.1.0 24 192.168.3.1
[r5]ip route-static 192.168.2.0 24 192.168.3.1

r2 ping  r7

r7 ping r2的环回

r7学到r1上的路由

r6  ping  r7

r7访问 r2、3、4的环回
