SecPath M9006 与对端ZX设备ipsec建立不成功问题处理经验案例

组网如下图

客户使用我司M9000设备与ZX友商设备对接IPSec，对接后发现设备IPSec SA无法正常建立，M9000配置如下

在M9000上开启调试开关，查看到有如下调试信息打出

根据调试信息分析可以看到，设备提示INVALID_ID_INFORMATION，根据报错，怀疑还是配置参数不匹配，导致IPSec无法正常建立。

通过检查设备配置，发现设备配置感兴趣流与对端不匹配

#
acl number 3010
 description to ipsec
 rule 4 permit ip vpn-instance DX source 192.168.2.1 0 destination 192.168.1.0 0.0.0.255
#

ZX侧感性趣流配置如下

$
!</switchvlan>
!<ipv4-acl>
ipv4-access-list 3010
  rule 10 permit ip 192.168.1.0 0.0.0.255 192.168.2.1 0.0.0.0
$

可以看到acl中一端配置了vpn实例，另一端没有配置vpn实例。

调整中兴侧配置，将acl配置vpn实例解决。
