MPLS VPN配置与分析 R1、R2、R3配置：（复习一下BGP的配置、简单了解一下MPLS的大体架构、以及基于运营商的MPLS优缺点分析） 技术前景以及应用： 需求分析：由于公司的规模不断变大，在不同地区已经建立分公司，要求分公司内部网络能够互访。各个分公司相距太远，无法直接铺设光纤，进行直连，借助于运营商的网络，传递分公司的路由信息，完成全互联。 MPLS VPN缺点分析：价格太贵 MPLS VPN优点分析：custom端配置简单，技术要求低。稳定性相对于ipsec VPN要高 ---------------------------------------------------R1-------------------------------------------------------------R1#sh run brief hostname R1ip cefno ip domain lookupip vrf a?rd 1:1?route-target export 1:1?route-target import 1:1!interface Loopback0?ip address 1.1.1.1 255.255.255.0!interface Serial1/0?ip address 12.1.1.1 255.255.255.0?mpls ip?serial restart-delay 0!interface Serial1/1?ip address 13.1.1.1 255.255.255.0?mpls ip!router rip?version 2?network 1.0.0.0?network 12.0.0.0?network 13.0.0.0?no auto-summaryline con 0?exec-timeout 0 0?logging synchronous?stopbits 1line aux 0?stopbits 1line vty 0 4end --------------------------------------------------R2--------------------------------------------------------------R2#show run brief hostname R2ip cefno ip domain lookupip vrf a?rd 1:1?route-target export 1:1?route-target import 1:1!ip vrf b?rd 2:2?route-target export 2:2?route-target import 2:2interface Loopback0?ip address 2.2.2.2 255.255.255.0interface Serial1/0?ip address 12.1.1.2 255.255.255.0?mpls ip?interface Serial1/1?ip vrf forwarding a?ip address 24.1.1.2 255.255.255.0?serial restart-delay 0!interface Serial1/2?ip vrf forwarding b?ip address 26.1.1.2 255.255.255.0?serial restart-delay 0!router rip?version 2?network 2.0.0.0?network 12.0.0.0?no auto-summary?!?address-family ipv4 vrf b?redistribute bgp 1 metric transparent?network 26.0.0.0?no auto-summary?exit-address-family?!??????? ?address-family ipv4 vrf a?redistribute bgp 1 metric transparent?network 24.0.0.0?no auto-summary?exit-address-family!router bgp 1?no synchronization?bgp log-neighbor-changes?neighbor 3.3.3.3 remote-as 1?neighbor 3.3.3.3 update-source Loopback0?no auto-
