ipsec1对多,只有一个能ping通.竞争占用隧道.如何解决

总部使用MSR3610,建立ipsec模板. 野蛮模式.

分支单位有多个使用msr810,4G路由器.除了Vlan-interface1的ip地址不同外,其他ipsec的配置数据都相同.

每个分支单位都可以单独成功建立ipsec,并能ping通总部的内部网络.

所有分支单位全部接入ipsec后,dis ike sa 能发现所有对等体.dis ipsec tunnel 可以看到全部隧道.

问题来了. 这些分支单位只有一个能ping通.谁优先接入隧道谁就能ping通.其他后接入隧道的就无法ping通.

在总部使用reset ipsec sa后, 原先不能ping的,就能ping了.也仅仅是一个. 本来可以ping的,就不能ping了.

就像是竞争的方式独占隧道.

这种问题如何解决.
