HCIP ---MPLS实验

实验题目：M PLS

实验目的：

1. R1与R5 MPLS VPN
2. R6与R7 MPLS VPN
3. R7可以访问R2/3/4的环回

实验拓扑：

实验思路：1.配置ip

2.pe端启ospf （让公网部分通）

3.搭建mpls

4.启mpls

5.pe与pe间建立bgp邻居关系

6.ce端与pe端交互路由  pe端与pe端重也交互路由

实验内容：

1. ip配置

[r1]interface LoopBack 0

[r1-LoopBack0]ip add 192.168.1.1 24

[r1]interface g0/0/0

[r1-GigabitEthernet0/0/0]ip add 192.168.2.1 24

[r2]interface LoopBack 0

[r2-LoopBack0]ip add 2.2.2.2 24

[r2-LoopBack0]quit

[r2]interface g0/0/1

[r2-GigabitEthernet0/0/1]ip add 23.1.1.1 24

[r3]interface LoopBack 0

[r3-LoopBack0]ip add 3.3.3.3 24

[r3-LoopBack0]quit

[r3]interface g0/0/0

[r3-GigabitEthernet0/0/0]ip add 23.1.1.2 24

[r3]interface g0/0/1

[r3-GigabitEthernet0/0/1]ip add 34.1.1.1 24

[r4]interface LoopBack 0

[r4-LoopBack0]ip add 4.4.4.4 24

[r4-LoopBack0]quit

[r4]interface g0/0/0

[r4-GigabitEthernet0/0/0]ip add 34.1.1.2 24

[r4]interface g0/0/2

[r4-GigabitEthernet0/0/0]ip add 47.1.1.1 24

[r5]interface LoopBack 0

[r5-LoopBack0]ip add 192.168.4.1 24

[r5-LoopBack0]quit

[r5]interface g0/0/0

[r5-GigabitEthernet0/0/0]ip add 192.168.3.2 24

[r6]interface LoopBack 0

[r6-LoopBack0]ip add 192.168.1.2 24

[r6-LoopBack0]quit

[r6]interface g0/0/0   

[r6-GigabitEthernet0/0/0]ip add 192.168.2.1 24

[r7]interface LoopBack 0

[r7-LoopBack0]ip add 192.168.4.2 24

[r7-LoopBack0]quit

[r7]interface g0/0/1

[r7-GigabitEthernet0/0/1]ip add 192.168.3.2 24

[r7-GigabitEthernet0/0/1]quit

[r7]interface g0/0/0

[r7-GigabitEthernet0/0/0]ip add 47.1.1.2 24

2.公网部分启IGP --ospf

[r2]ospf 1 router-id 2.2.2.2

[r2-ospf-1]area 0

[r2-ospf-1-area-0.0.0.0]network 2.2.2.2 0.0.0.0

[r2-ospf-1-area-0.0.0.0]network 23.1.1.1 0.0.0.0

[r3]ospf 1 router-id 3.3.3.3

[r3-ospf-1]area 0

[r3-ospf-1-area-0.0.0.0]network 3.3.3.3 0.0.0.0

[r3-ospf-1-area-0.0.0.0]network 23.1.1.2 0.0.0.0

[r3-ospf-1-area-0.0.0.0]network 34.1.1.1 0.0.0.0

[r4]ospf 1 router-id 4.4.4.4

[r4-ospf-1]area 0

[r4-ospf-1-area-0.0.0.0]network 4.4.4.4 0.0.0.0

[r4-ospf-1-area-0.0.0.0]network 34.1.1.2 0.0.0.0

[r4-ospf-1-area-0.0.0.0]network 47.1.1.1 0.0.0.0

为了保证安全 把g0/0/2调成沉默接口

被动接口(沉默接口)--仅接收不发送路由协议信息；用于连接用户终端的接口，不得用于连接邻居路由器的接口，否则无法建立邻居关系；

[r4-ospf-1]silent-interface GigabitEthernet 0/0/2

[r4-ospf-1]quit

同是也在接口上做好认证

[r4]interface g0/0/2

[r4-GigabitEthernet0/0/2]ospf authentication-mode md5 1 cipher 123456

然后r7一条缺省指向r4

[r7]ip route-static 0.0.0.0 0 47.1.1.1

此时已经可以互相访问成功：

3.公网部分启MPLS

[r2]mpls lsr-id 2.2.2.2

[r2]mpls

Info: Mpls starting, please wait... OK!

[r2-mpls]mpls ldp

[r2-mpls-ldp]quit

[r2]interface g0/0/1

[r2-GigabitEthernet0/0/1]mpls

[r2-GigabitEthernet0/0/1]mpls ldp

[r3]mpls lsr-id 3.3.3.3

[r3]mpls

Info: Mpls starting, please wait... OK!

[r3-mpls]mpls ldp

[r3-mpls-ldp]quit

[r3]interface g0/0/0

[r3-GigabitEthernet0/0/0]mpls ldp

[r3-GigabitEthernet0/0/0]quit

[r3]interface g0/0/1

[r3-GigabitEthernet0/0/1]mpls

[r3-GigabitEthernet0/0/1]mpls ldp

[r4]mpls lsr-id 4.4.4.4

[r4]mpls

Info: Mpls starting, please wait... OK!

[r4-mpls]mpls ldp

[r4-mpls-ldp]quit

[r4]interface g0/0/0

[r4-GigabitEthernet0/0/0]mpls

[r4-GigabitEthernet0/0/0]mpls ldp

4.配置MPLS VPN

(1)先配置1和5

[r2]ip -instance a1

[r2--instance-a1]ipv4

[r2--instance-a1]ipv4-family

[r2--instance-a1-af-ipv4]route-distinguisher 1:1

[r2--instance-a1-af-ipv4]-target 1:1

[r2]interface g0/0/0

[r2-GigabitEthernet0/0/0]ip binding -instance a1

Info: All IPv4 related configurations on this interface are removed!

Info: All IPv6 related configurations on this interface are removed!

[r2-GigabitEthernet0/0/0]ip add 192.168.2.2 24

 

此时r1与r2可以互相访问

但r2 ping r1时：要在空间中ping

[r4]ip -instance a2

[r4--instance-a2]ipv4-family

[r4--instance-a2-af-ipv4]route-distinguisher 1:1

[r4--instance-a2-af-ipv4]-target 1:1

[r4]interface g0/0/1

[r4-GigabitEthernet0/0/1]ip binding -instance a2

Info: All IPv4 related configurations on this interface are removed!

Info: All IPv6 related configurations on this interface are removed!

[r4-GigabitEthernet0/0/1]ip add 192.168.3.1 24

（2）再配置R6和R7

[r2]ip -instance b1

[r2--instance-b1]ipv4

[r2--instance-b1]ipv4-family

[r2--instance-b1-af-ipv4]route-distinguisher 2:2

[r2--instance-b1-af-ipv4]-target 2:1

[r2]interface g0/0/2

[r2-GigabitEthernet0/0/2]ip binding -instanceb1

Info: All IPv4 related configurations on this interface are removed!

Info: All IPv6 related configurations on this interface are removed!

[r2-GigabitEthernet0/0/2]ip add 192.168.2.2 24

[r4]ip -instance  b2

[r4--instance-b2]ipv4-family

[r4--instance-b2-af-ipv4]route-distinguisher 2:2

[r4--instance-b2-af-ipv4]-target 2:1

[r4]interface e4/0/0

[r4-Ethernet4/0/0]ip binding -instance b2

Info: All IPv4 related configurations on this interface are removed!

Info: All IPv6 related configurations on this interface are removed!

[r4-Ethernet4/0/0]ip add 192.168.3.1 24

 

 

5.PE与PE间建立MP-BPG邻居关系

[r2]bgp 2   

[r2-bgp]router-id 2.2.2.2

[r2-bgp]peer 4.4.4.4 as-number 2

[r2-bgp]peer 4.4.4.4 connect-interface LoopBack 0

[r2-bgp]ipv4-family v4               

[r2-bgp-af-v4]peer 4.4.4.4 enable

[r4]bgp 2

[r4-bgp]router-id 4.4.4.4

[r4-bgp]peer 2.2.2.2 as-number 2

[r4-bgp]peer 2.2.2.2 connect-interface LoopBack 0

[r4-bgp]ipv4-family v4

[r4-bgp-af-v4]peer 2.2.2.2 enable

6.CE端与PE端交互路由

（1）先配置r1与r5    要求使用静态路由

[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

[r2]ip route-static -instance a1 192.168.1.0 24 192.168.2.1

[r2]bgp 2

[r2-bgp]ipv4-family -instance a1

[r2-bgp-a1]import-route direct

[r2-bgp-a1]import-route static

[r5]ip route-static 192.168.1.0 24 192.168.3.1

[r5]ip route-s

[r5]ip route-static 192.168.2.0 24 192.168.3.1

[r4]ip route-static -instance a2 192.168.4.0 24 192.168.2.2

[r4]bgp 2

[r4-bgp]ipv4-family -instance a2

[r4-bgp-a2]import-route direct

[r4-bgp-a2]import-route static

此时重发布得到的路由

 

R5也ping 通了R1

（2）再配置r6和r7   r6用rip  r7用ospf

[r6]rip  1

[r6-rip-1]ver 2

[r6-rip-1]network 192.168.1.0

[r6-rip-1]network 192.168.2.0

[r2]rip 1 -instance b1

[r2-rip-1]network 192.168.2.0

[r7]ospf 1 router-id 7.7.7.7

[r7-ospf-1]area 0

[r7-ospf-1-area-0.0.0.0]network 192.168.4.1 0.0.0.0

[r7-ospf-1-area-0.0.0.0]network 192.168.3.2 0.0.0.0

[r4]ospf 2 -instance b2

[r4-ospf-2]area 0

[r4-ospf-2-area-0.0.0.0]network 192.168.3.1 0.0.0.0

重发布：

[r2]rip 1

[r2-rip-1]import-route bgp

[r2-rip-1]quit

[r2]bgp 2

[r2-bgp]ipv4-family -instance b1

[r2-bgp-b1]import-route rip

[r4]bgp 2

[r4-bgp]ipv4-family -instance b2

[r4-bgp-b2]import-route ospf 2

[r4-bgp-b2]quit

[r4]ospf 2 -instance b2

[r4-ospf-2]import-route bgp
