SR6608+带源ping无法ping通上联的网段地址带loopback22地址能通

下联CE交换机可以ping通，带实例jsjis带loopback22源ping上联网段测试地址也通，但是带实例jsjis带互联口Gi2/0/0的地址去ping上联测试网段地址不通。到上联是走实例jsjis的vpn默认路由的

-------关键配置如下------

# hostname P-js-router 

#实例jsjis 

ip vpn-instance jsjis

 route-distinguisher 57689:17 

  vpn-target 57689:17 import-extcommunity 

  vpn-target 57689:17 export-extcommunity 

 #用于测试的loopback地址 

interface LoopBack22 

 ip binding vpn-instance jsjis 

 ip address 30.32.137.22 255.255.255.255 

 #和下联交换机的互联接口 

interface GigabitEthernet2/0/0 

 port link-mode route 

 combo enable fiber 

 duplex full speed 1000 

 ip binding vpn-instance jsjis 

 ip address 192.168.16.49 255.255.255.252 

# bgp 16533 

-----此处略------ 

 address-family vpnv4 

  reflector cluster-id 1954407 

 undo policy vpn-target 

 peer VRR enable 

 peer VRR-CLIENT enable 

 peer VRR-CLIENT reflect-client 

 #

 ip vpn-instance jsjis 

 # 

 address-family ipv4 unicast

  import-route direct 

  import-route static 

 #192.168.6.50是下联CE交换机的互联地址

 ip route-static vpn-instance jsjis 30.32.137.0 25 192.168.6.50 

 ------路由-----------
