使用BGP、RIP和OSPF的MPLS VPN网络

Question

我正在配置MPLS网络。

下面是我正在做的工作：

从CE1，我希望能够平移CE2的回环地址，反之亦然，这还不可能，我不知道我在哪里出了问题……我迄今所采取的步骤如下：

前提条件：

• 在P和PE路由器上启用OSPF，在网络内广告加上回环
• 在P和PE路由器上启用MPLS

采取的步骤：

1. 在PE和CE路由器上，我启用了RIP V2
2. 在这两个PE路由器上，我为客户端启用了VRF (在PE2上重复)PE1(配置)#ip vrf client1 PE1(config-vrf)#rd 999:1 PE1(config-vrf)#PE1(config-vrf)#PE1 64999:1 PE1(config-vrf)#PE1--目标导入64999:1
3. 将两个PE路由器上的VRF分配给CE路由器面临的接口
4. 在两个PE路由器上设置基本BGP，我将列出两个PE路由器的运行配置：

1. 将RIP配置为使用用于PE1和PE2的VRF表。PE1(配置)#路由器撕裂PE1(配置-路由器)#地址-家庭ipv4 vrf client1 PE1(配置-路由器-af)#第2版(配置-路由器-af)#网络10.0.0.0 PE1(配置-路由器-af)#无自动摘要
2. 路线的重新分配
   • 到BGP的旅行路线
   • 到RIP的BGP路线

在进行了上述配置之后，我运行了以下命令.

CE1 -只能在CE1和CE2上看到连接的路由

     10.0.0.0/30 is subnetted, 2 subnets
C       10.1.1.8 is directly connected, Loopback0
C       10.1.1.0 is directly connected, FastEthernet0/0

PE1

PE1#show ip route
Gateway of last resort is not set

     1.0.0.0/32 is subnetted, 1 subnets
C       1.1.1.1 is directly connected, Loopback0
     2.0.0.0/32 is subnetted, 1 subnets

O       3.3.3.3 [110/21] via 192.168.1.2, 01:02:04, FastEthernet0/1
     4.0.0.0/32 is subnetted, 1 subnets
O       4.4.4.4 [110/31] via 192.168.1.2, 01:02:04, FastEthernet0/1
     192.168.1.0/30 is subnetted, 3 subnets
O       192.168.1.8 [110/30] via 192.168.1.2, 01:02:06, FastEthernet0/1
C       192.168.1.0 is directly connected, FastEthernet0/1
O       192.168.1.4 [110/20] via 192.168.1.2, 01:02:06, FastEthernet0/1

和

PE1#show ip route vrf client1
     10.0.0.0/30 is subnetted, 2 subnets
R       10.1.1.8 [120/1] via 10.1.1.1, 00:00:18, FastEthernet0/0
C       10.1.1.0 is directly connected, FastEthernet0/0

PE2

PE2#show ip route

     1.0.0.0/32 is subnetted, 1 subnets
O       1.1.1.1 [110/31] via 192.168.1.10, 01:08:58, FastEthernet0/1
     2.0.0.0/32 is subnetted, 1 subnets
O       2.2.2.2 [110/21] via 192.168.1.10, 01:09:08, FastEthernet0/1
     3.0.0.0/32 is subnetted, 1 subnets
O       3.3.3.3 [110/11] via 192.168.1.10, 01:09:08, FastEthernet0/1
     4.0.0.0/32 is subnetted, 1 subnets
C       4.4.4.4 is directly connected, Loopback0
     192.168.1.0/30 is subnetted, 3 subnets
C       192.168.1.8 is directly connected, FastEthernet0/1
O       192.168.1.0 [110/30] via 192.168.1.10, 01:08:59, FastEthernet0/1
O       192.168.1.4 [110/20] via 192.168.1.10, 01:09:09, FastEthernet0/1

和

PE2#show ip route vrf client2
     10.0.0.0/30 is subnetted, 3 subnets
B       10.1.1.8 [200/1] via 1.1.1.1, 00:55:41
B       10.1.1.0 [200/0] via 1.1.1.1, 00:55:41
C       10.1.1.4 is directly connected, FastEthernet0/0

• 为什么我只看到PE1的RIP路线？在PE2中只有BGP路线？
• 我应该看到从PE1和2到CE网络的BGP和RIP的路由吗？
• 我错过了什么/做错了什么不让我从CE1到CE2，反之亦然？

在RIP配置下

Answer 2

PE2丢失(在RIP地址-家庭ipv4 vrf client2下)
