MPLS学习笔记实验

内网先运行igp

R1:
router ospf 110
router-id 1.1.1.1 
network 1.1.1.1 0.0.0.0 area 0
network 12.1.1.1 0.0.0.0 area 0
network 13.1.1.1 0.0.0.0 area 0

r2
router ospf 110
router-id 2.2.2.2 
network 2.2.2.2 0.0.0.0 area 0
network 12.1.1.2 0.0.0.0 area 0
netw

r3:
router ospf 110
router-id 3.3.3.3
network 13.1.1.3 0.0.0.0 area 0
network 3.3.3.3 0.0.0.0  area 0

启用mpls

r1
ip cef 
mpls label protocol ldp // 思科需要敲  数据层面：启用mpls的转发机制，在发数据的时候尝试打标。 ldp/tdp的宣告 新设备默认ldp
mpls ldp router-id loopback 0 force  // force 无论当前是否建立ldp邻居 都拿loopback0 来做传输地址
mpls ip 

int  e0/0
mpls ip 

r2 
ip cef 
mpls ip 
mpls label protocol ldp
mpls ldp router-id loopback 0 force 

int e0/1 
mpls ip 

r3 
ip cef
mpls ip
mpls label protocol ldp 
mpls ldp  router-id loopback 0 force 
int e0/0
mpls ip 

查看命令

show mpls ldp neighbor 
show mpls ldp bindings 查看FIB
show mpls forwarding-table

建立bgp

r4:
router bgp  4  //as号 
no auto-summary 
no synchronization
bgp router-id 4.4.4.4 
neighbor 24.1.1.2 remote-as 10  //默认自动建立ipv4的邻居关系。
network 8.8.8.0 mask 255.255.255.0

r2
router bgp 10
no auto-summary 
no synchronization
bgp router-id 2.2.2.2 
neighbor 24.1.1.4 remote-as 4
neighbor 3.3.3.3 remote-as 10
neighbor 3.3.3.3 updatesource loopback 0
neighbor 3.3.3.3 next-hop-self 

r3
router bgp 10
no auto-summary 
no synchronization
bgp router-id 3.3.3.3
neighbor 35.1.1.5 remote-as 5
neighbor 2.2.2.2 update-source 3.3.3.3 
neighbor 2.2.2.2 remote-as 10
neighbor 2.2.2.2 next-hop-self 

r5 
router bgp 5
no auto-summary 
no synchronization
bgp router-id 5.5.5.5
neighbor 35.1.1.3 remote-as  10
network 9.9.9.0 mask 255.255.255.0

基于华为：

在r1,2,3上启用igp

启mpls

r1 
mpls // 全局启m用mpls
mpls lsr-id  1.1.1.1 //传输地址
mpls 
mpls ldp
int g0/0/0-1
  mpls // 数据层面
 mpls ldp //控制层面

r2 r3  
mpls 
mpls lsr-id x.x.x.x
mpls 
mpls ldp
int g0/0/n
mpls 
mpls ldp

全 迭代命令：route recursive-lookup tunnel

查看display mpls ldp per /verbose
display mpls lsp 标签交换路径

启用bgp
