拓扑图

基本思路：

• 第一步：配置好各个接口的IP地址
• 第二步：在R1和R4上配置静音路由，仅需要在R1和R4上配置，R2和R3不需要
• 第三步：配置lsr-id启动（全局启动/接口启动）mpls
• 第四步：配置静态的LDP,注意，是来回呀

基础配置

R1

sysn R1
dhcp enable
int l0
ip add 10.0.1.1 32
int g0/0/1
ip add 192.168.10.1 24
dhcp select interface
int g0/0/0
ip add 10.0.12.1 24

R2:

ip add 10.0.2.2 32
int g0/0/0
ip add 10.0.12.2 24

MPLS 基础配置

MPLS:
	R1:
		mpls lsr-id 10.0.1.1
		mpls
		quit
		int g0/0/0
			mpls
		int g0/0/1
			mpls
	R2：
		mpls lsr-id 10.0.2.2
		mpls
		quit
		int g0/0/0
			mpls
		int g0/0/1
			mpls
	R3：
		mpls lsr-id 10.0.3.3
		mpls
		quit
		int g0/0/0
		mpls
		int g0/0/1
		mpls
	R4：
		mpls lsr-id 10.0.4.4
		mpls
		quit
		int g0/0/0
		mpls
		int g0/0/1
		mpls

MPLS静态LSP的配置

R1：
	static-lsp ingress 1to2 destination 192.168.20.0 24 nexthop 10.0.12.2 out-lab 1002
R2：
	static-lsp transit 1to2 incoming-interface g0/0/0 in-label 1002 nexthop 10.0.23.3 out-label 1003
R3
	static-lsp transit 1to2 incoming-interface g0/0/0 in-label 1003 nexthop 10.0.34.4 out-label 1004
R4:
	static-lsp egress 1to2 incoming-interface g0/0/0 in-label 1004 
	
	
R4:
	static-lsp ingress 2to1 destination 192.168.10.0 24 nexthop 10.0.34.3 out-label 1013
R3:
	static-lsp transit 2to1 incoming-inter g0/0/1 in-label 1013 nexthop 10.0.23.2 out-label 1012
R2:
	static-lsp transit 2to1 incoming-inter g0/0/1 in-label 1012 nexthop 10.0.12.1 out-label 1011
	
R1:
	static-lsp egress 2to1 incoming-inter g0/0/0 in-label 1011
