6VPE+Mpls option C1 方案

拓扑图规划如图所示

首先先配置CE设备

ipv6

interface GigabitEthernet0/0/0

 ipv6 enable

 ipv6 address 2000:17::7/64

interface LoopBack0

 ipv6 enable

 ipv6 address 2000:7::7/128

并且与PE建立ipv6的bgp邻居 

bgp 65000

 router-id 7.7.7.7

 peer 2000:17::1 as-number 100

 #

 ipv4-family unicast

  undo synchronization

 #

 ipv6-family unicast

  undo synchronization

  network 2000:7::7 128

  peer 2000:17::1 enable

PE设备配置ipv6地址以及ipv4地址并且跑ospf以及mpls ldp

interface GigabitEthernet0/0/0

 ipv6 enable

 ipv6 address 2000:17::1/64

interface GigabitEthernet0/0/1

ip address 12.0.0.1 255.255.255.0

mpls

mpls ldp

interface LoopBack0

 ip address 1.1.1.1 255.255.255.255

ospf 1

 area 0.0.0.0

  network 1.1.1.1 0.0.0.0

  network 12.0.0.1 0.0.0.0

mpls lsr-id 1.1.1.1

mpls

mpls ldp

P设备配置：

interface GigabitEthernet0/0/0

 ip address 12.0.0.2 255.255.255.0

 mpls

 mpls ldp

#

interface GigabitEthernet0/0/1

 ip address 23.0.0.2 255.255.255.0

 mpls

 mpls ldp

interface LoopBack0

 ip address 2.2.2.2 255.255.255.255

ospf 1

 area 0.0.0.0

  network 0.0.0.0 255.255.255.255

mpls lsr-id 2.2.2.2

mpls

mpls ldp

ASBR同理：

interface GigabitEthernet0/0/0

 ip address 23.0.0.3 255.255.255.0

 mpls

 mpls ldp

#

interface GigabitEthernet0/0/1

 ip address 34.0.0.3 255.255.255.0

 mpls

interface LoopBack0

 ip address 3.3.3.3 255.255.255.255

#ospf 1

 area 0.0.0.0

  network 3.3.3.3 0.0.0.0

  network 23.0.0.3 0.0.0.0

#

mpls lsr-id 3.3.3.3

mpls

#

mpls ldp

AS200的设备同理，这里不再赘述

创建实例并且绑定接口

ip vpn-instance 10

 ipv6-family

  route-distinguisher 100:100

  vpn-target 100:100 export-extcommunity

  vpn-target 100:100 import-extcommunity

interface GigabitEthernet0/0/0

 ip binding vpn-instance 10

然后R1与R6建立MP-BGP邻居，传递VPNV6路由，其余的和MPLS  VPN C1一样

bgp 100

 router-id 1.1.1.1

 peer 3.3.3.3 as-number 100

 peer 3.3.3.3 connect-interface LoopBack0

 peer 6.6.6.6 as-number 200

 peer 6.6.6.6 ebgp-max-hop 255

 peer 6.6.6.6 connect-interface LoopBack0

 #

 ipv4-family unicast

  undo synchronization

  peer 3.3.3.3 enable

  peer 3.3.3.3 label-route-capability

  peer 6.6.6.6 enable

 #

 ipv6-family unicast

  undo synchronization

  peer 3.3.3.3 enable

  peer 3.3.3.3 label-route-capability

 #

 ipv6-family vpnv6

  policy vpn-target

  peer 6.6.6.6 enable

 #

 ipv6-family vpn-instance 10

  peer 2000:17::7 as-number 65000

ASBR之间的策略

route-policy asbr permit node 10

 apply mpls-label

#

route-policy pe permit node 10

 if-match mpls-label

 apply mpls-label

应用策略

peer 1.1.1.1 route-policy pe export

peer 34.0.0.4 route-policy asbr export

并且打开标签交换能力

peer 1.1.1.1 label-route-capability

peer 34.0.0.4 label-route-capability

在ASBR之间network pe的环回口，让pe之间互相学习到环回口路由用来建立mp-bgp邻居，传递vpnv6路由

 network 1.1.1.1 255.255.255.255

在pe上查看bgp vpnv6邻居

查看vpnv6的路由

Ce互相ping一下

查看vpnv6的标签

去往2000：8：：8的出标签为1027，这是私网标签

再查看BGP分配的标签以及mpls ldp分配的标签
