MPLS-静态LSP

实验需求:
1、配置IP地址
2、全网部署RIP 1
3、配置MPLS
4、验证
具体配置:

• 配置IP地址
  

AR1
interface GigabitEthernet0/0/0
ip address 10.1.12.1 24
AR2
interface GigabitEthernet0/0/0
ip address 10.1.12.2 24
interface GigabitEthernet0/0/1
ip address 10.1.23.2 24
AR3
interface GigabitEthernet0/0/1
ip address 10.1.23.3 24
interface GigabitEthernet0/0/0
ip address 10.1.34.3 24
AR4
interface GigabitEthernet0/0/0
ip address 10.1.34.4 24
interface loopback 0
ip address 10.1.4.4 32

• 全网部署RIP 1
  

AR1、AR2、AR3、AR4相同的rip配置
rip 1
version 2
network 10.0.0.0
在AR1上检查全网的连通性

• 配置MPLS
  

AR1
[R1]mpls lsr-id 1.1.1.1 //配置MPLS的LSR-ID
[R1]mpls //全局模式开启MPLS
[R1]interface GigabitEthernet0/0/0
[R1-GigabitEthernet0/0/0]mpls //路由器互联接口开启MPLS
[R1]static-lsp ingress 1234 destination 10.1.4.4 32 outgoing-interface GigabitEthern
et0/0/0 nexthop 10.1.12.2 out-label 102
AR2
[R2]mpls lsr-id 2.2.2.2
[R2]mpls
[R2]interface GigabitEthernet0/0/0
[R2-GigabitEthernet0/0/0]mpls
[R2]interface GigabitEthernet0/0/1

AR3
[R3]mpls lsr-id 3.3.3.3
[R3]mpls
[R3]interface GigabitEthernet0/0/0
[R3-GigabitEthernet0/0/0]mpls
[R3]interface GigabitEthernet0/0/1

AR4
[R4]mpls lsr-id 4.4.4.4
[R4]mpls
[R4]interface GigabitEthernet0/0/0
[R4-GigabitEthernet0/0/0]mpls
[R4]static-lsp egress 1234 incoming-interface GigabitEthernet0/0/0 in-label 304

• 验证
  

（1）在R1上查看mpls的配置结果，可以看到标签、出接口和mpls的状态。

• 通过在R1上PING 10.1.4.4逐跳抓包查看标签是否正确，首先抓包方法是右击路由器，在弹出的会话窗口内选择数据抓包，然后进一步选择接口，如下图所示：
  

接着就是在R1、R2、R3上逐跳抓包：
R1

R2

R3

从抓包的情况来看，在转发过程中是带着标签转发的
