HCIP----MPLS实验

1. 题目及要求

1. R1与R5MPLS VPN
2. R4与R7MPLS VPN
3. R7可以访问R2/3/4的环回

2. 完成拓扑设计

3. 配置底层IP

配置ISP的底层IP

先配置公网的IP地址及AR2,AR3和AR4的地址
其中AR2左接口和AR4右接口不属于公网，属于私网的IP地址,因此配置时需要注意
AR2
AR3

AR4

配置私网IP

AR1

AR6

AR5
AR7

配置IGP路由—启OSPF

AR2

AR3

AR4

AR7

启动MPLS

AR2


AR3和AR4同理
配置完成后检查OSPF的邻居表

以及检查MPLS LDP表

注意：默认只给32位的分标签

配置MPLS

AR2

[r2]ip vpn-instance b1
[r2-vpn-instance-b1]ipv4-family 
[r2-vpn-instance-b1-af-ipv4]route-distinguisher 1:1
[r2-vpn-instance-b1-af-ipv4]vpn-target 1:1
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip binding vpn-instance b1
[r2-GigabitEthernet0/0/0]ip address 192.168.2.2 24

配置完成后查看接口有IP但是查看路由表中不存在该接口的IP

[r2]ip vpn-instance a1
[r2-vpn-instance-a1]ipv4-family 
[r2-vpn-instance-a1-af-ipv4]route-distinguisher 2:2
[r2-vpn-instance-a1-af-ipv4]vpn-target 2:2
[r2-vpn-instance-a1-af-ipv4]q
[r2-vpn-instance-a1]q
[r2]int g0/0/2
[r2-GigabitEthernet0/0/2]ip binding vpn-instance a1
[r2-GigabitEthernet0/0/2]ip address 192.168.2.2 24

同理配置AR4

AR2与AR4建立MP-BGP邻居关系

AR2

[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 vpnv4 
[r2-bgp-af-vpnv4]peer 4.4.4.4 enable

AR4

[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 vpnv4        
[r4-bgp-af-vpnv4]peer 2.2.2.2 enable

4. B区域使用静态路由

使用静态路由

AR1

[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

AR2

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

AR5

[r5]ip route-static 192.168.2.0 24 192.168.3.2
[r5]ip route-static 192.168.1.0 24 192.168.3.2

AR4与AR2同理

重发布

AR2和AR4同理

[r2]bgp 2
[r2-bgp]ipv4-family vpn-instance b1
[r2-bgp-b1]import-route static 
[r2-bgp-b1]import-route direct

检查AR2和AR4的路由表

5. A区域

A1区域使用RIP

AR6启rip

[r6]rip 1        
[r6-rip-1]version 2
[r6-rip-1]network 192.168.1.0 
[r6-rip-1]network 192.168.2.0

AR2

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

A2 区域启OSPF

AR7启ospf

[r7]ospf 2 router-id 7.7.7.77
[r7-ospf-2]area 0
[r7-ospf-2-area-0.0.0.0]network 192.168.4.2 0.0.0.0
[r7-ospf-2-area-0.0.0.0]network 192.168.3.1 0.0.0.0

AR4

[r4]ospf 2 vpn-instance a2 
[r4-ospf-2]area 0
[r4-ospf-2-area-0.0.0.0]network 192.168.3.2 0.0.0.0

AR2与AR4进行双向重发布

AR2

[r2]rip 1 vpn-instance a1
[r2-rip-1]import-route bgp 
[r2-rip-1]q
[r2]bgp 2
[r2-bgp]ipv4-family vpn-instance a1
[r2-bgp-a1]import-route rip 1

AR4

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

检查AR2和AR4的路由表

6. 检验
