[讨论/求助] Side2Side 問題

Hi

小弟最近遇到了個問題
我目前三個點互作side2side VPN
ASA-3後段是一段Server用網段10.222.0.0/16
一段是SSLVPN用的192.168.78.0/24
分別與ASA-1和ASA-2做side2side
正常設定都沒問題
但ASA-3與ASA-1建立的部份在過一段時間後
ASA-3後SSLVPN用的網段192.168.78.0/24會突然的不通連不到
但ASA-3與ASA-1的都沒問題,設定值是一樣的
需在其中一邊的設備上下clear ipsec sa peer x.x.x.x
讓ASA-3與ASA-1重建才會正常
但一段時間後就又不能了
指令檢查是正常的
ASA-3# sho crypto isakmp sa

IKEv1 SAs:

   Active SA: 3
    Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 3

1   IKE Peer: 6.22.15.250
    Type    : L2L             Role    : initiator
    Rekey   : no              State   : MM_ACTIVE
2   IKE Peer: 12.21.101.253
    Type    : L2L             Role    : responder
    Rekey   : no              State   : MM_ACTIVE
3   IKE Peer: 6.22.15.220
    Type    : L2L             Role    : responder
    Rekey   : no              State   : MM_ACTIVE

There are no IKEv2 SAs

show ipsec sa 時正常的狀況下是能看到192.168.78.0/24的資訊
ASA-3# show ipsec sa peer 6.22.15.220

然後有問題時會跳出以下的log
3Oct 07 201617:50:44Tunnel Manager has failed to establish an L2L SA.  All configured IKE versions failed to establish the tunnel. Map Tag= Outsite_map0.  Map Sequence Number = 3.

3Oct 07 201617:50:44Group = 6.22.15.220, IP = 6.22.15.220, Removing peer from correlator table failed, no match!
3Oct 07 201617:50:44Group = 6.22.15.220, IP = 6.22.15.220, QM FSM error (P2 struct &0x00007fffe32afdd0, mess id 0xa971c2f8)!
請高手求解
