HCIP——MPLS VPN实验

一、实验

1、实验拓扑及要求

使用MPLS VPN实现全网可达

2、实验拓扑搭建以及IP地址划分

3、实验步骤

1、配置永不超时以及接口IP地址

实验一结束。

二、实验二

1、实验拓扑及要求

使用MPLS VPN全网可达

2、实验拓扑搭建以及拓扑划分

3、实验步骤

1、配置永不超时以及接口环回

4、配置BGP非直连建邻，并打开vpnV4路由传递功能

R2：

[R2]bgp 1
[R2-bgp]router-id 2.2.2.2
[R2-bgp]peer 5.5.5.5 as-number 1
[R2-bgp]peer 5.5.5.5 connect-interface LoopBack 0
[R2-bgp]peer 6.6.6.6 as-number 1

5、在PE端做MPLS VPN

R2：

[R2]ip vpn-instance 1
[R2-vpn-instance-1]route-distinguisher 2:2
[R2-vpn-instance-1-af-ipv4]vpn-target 5:5 6:6 import-extcommunity 
[R2-vpn-instance-1-af-ipv4]vpn-target 2:2 export-extcommunity 
[R2-vpn-instance-1-af-ipv4]q
[R2-vpn-instance-1]q
[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]undo ip address 
[R2-GigabitEthernet0/0/0]ip binding vpn-instance 1
[R2-GigabitEthernet0/0/0]ip address 12.1.1.2 24

[R5-vpn-instance-2-af-ipv4]vpn-target 2:2 6:6 import-extcommunity 
[R5-vpn-instance-2-af-ipv4]q
[R5-vpn-instance-2]q
[R5]
[R5]int g0/0/1
[R5-GigabitEthernet0/0/1]undo ip address 
[R5-GigabitEthernet0/0/1]ip binding vpn-instance 2
[R5-GigabitEthernet0/0/1]ip address 57.1.1.1 24

R2：

[R2]ip route-static vpn-instance 1 1.1.1.1 32 12.1.1.1
[R2]bgp 1
[R2-bgp]ipv4-family vpn-instance 1

8、给R6以及R8配置OSPF并双向重发布

R6：

[R6]ospf 2 vpn-instance 3
[R6-ospf-2]area 0
[R6-ospf-2-area-0.0.0.0]network 68.1.1.1 0.0.0.0
