S5700交换机的vpn实例路由不能引入到ospf表问题中

SW11的路由表:

[SW11]dis ip routing-table vpn-instance vpna

Route Flags: R - relay, D - download to fib

-----------------------------------------------------------------------

-------

Routing Tables: vpna

         Destinations : 2        Routes : 2       

Destination/Mask    Proto   Pre  Cost      Flags NextHop        

Interface

     172.16.3.0/24  Direct  0    0           D   172.16.3.2     

Vlanif30

     172.16.3.2/32  Direct  0    0           D   127.0.0.1      

Vlanif30

[SW11]dis ip routing-table vpn-instance vpnb

Route Flags: R - relay, D - download to fib

-----------------------------------------------------------------------

Routing Tables: vpnb

         Destinations : 2        Routes : 2       

Destination/Mask    Proto   Pre  Cost      Flags NextHop        

Interface

     172.17.4.0/24  Direct  0    0           D   172.17.4.2

在MCE上:

1)Ospf 100 vpn-instance vpna

vpn-instance-capability simple

2)Ospf 100 vpn-instance vpnb

vpn-instance-capability simple

1、rip和ospf路由都正确宣告

2、vpn配置无错误

3、MCE有两个vpn实例路由,但PE只有ospf的直连路由,无两个vpn实例路由

总结:当在MCE(Multi-VPN-Instance CE)设备上支持VPN多实例时,需要取消环路检查。

此命令只在OSPF的VPN实例下才起作用。
