mpls vpn配置实例_ip地址

思路:

1、将IBGP的内部路由tcp联通,建议使用ISIS协议

isis xxx //xxx进程号

is-level level-2 

network-entity 49.0001.0010.0100.1001.00

2、将MPLS配置完成,使用LDP

全局模式

mpls lsr-id x.x.x.x

mpls

mpls LDP 

接口模式

mpls

mpls LDP 

3、常见实例VRF

ip vpn-instance XYZ

ipv4-family

 route-distinguisher 4:1  //RD,路由区分付,vpnv4的地址为:rd+ip地址

 vpn-target 4:1 export-extcommunity  //RT

 vpn-target 4:1 5:3 import-extcommunity  //RT

4、将实例与接口绑定

interface GigabitEthernet0/0/0

ip binding vpn-instance XYZ

ip address 192.168.1.1 255.255.255.0 

5、配置mp-bgp

bgp 200

router-id 1.1.1.1

undo default ipv4-unicast

peer 3.3.3.3 as-number 200  

peer 3.3.3.3 connect-interface LoopBack0

#

ipv4-family unicast

 undo synchronization

 undo peer 3.3.3.3 enable

#  

ipv4-family vpnv4

 policy vpn-target

 peer 3.3.3.3 enable

#

ipv4-family vpn-instance XYZ 

//ipv4-family vpn-instance vpn-instance-name  // 将指定的VPN实例与IPv4地址族进行关联,并进入BGP-VPN实例IPv4地址族视图。

 import-route static

6、配置静态路由

PE:

ip route-static vpn-instance XYZ 4.4.4.4 255.255.255.255 GigabitEthernet0/0/0 19

2.168.1.14

CE:

ip route-static 0.0.0.0 0.0.0.0 GigabitEthernet0/0/0 192.168.1.1
