Checkpoint防火墻ClusterXL 故障之FIB Problem問題解決

辦公網有兩臺CheckPoint防火墻做cluster的HA主備模式，Custer-HA出現故障現象如下（其中一臺CP-248狀態為down，一邊CP-246為active），導致CP-246和CP-248的cluster的HA準備切換不成功。

[NJZQ-CP-248]# cphaprob stat  

Cluster Mode:   New High Availability (Active Up)

Number    Unique Address  Assigned Load   State      

1       19.19.19.246    100%            Active     

2 (local) 19.19.19.248    0%              Down   

[NJZQ-CP-248]# cphaprob list  //該命令非常有用，用于查找出CP防火墻cluster的監控的關鍵組件（cp稱為Device）

對應的CP-246的顯示如下：

[NJZQ-CP-246]# cphaprob stat

Cluster Mode:   New High Availability (Active Up)

Number    Unique Address  Assigned Load   State      

1 (local) 19.19.19.246    100%            Active     

2     19.19.19.248    0%              Down 

并且發現對應的CP-246的cphaprob list顯示并無異常，均為OK。

[Expert@NJZQ-CP-246]# cphaprob list

發現以上的故障現象后，對CP-248的clusterXL進行重啟如下：

[NJZQ-CP-248]# expert

Enter expert password:

You are in expert mode now.

[Expert@NJZQ-CP-248]# clusterXL_admin down

Setting member to administratively downstate ...

Member current state is Down

[Expert@NJZQ-CP-248]# clusterXL_admin up 

Setting member to normal operation ...

Member current state is Down

Operation failed: member is still down, run 'cphaproblist' for further details

重啟后，仍然不成功。

從網上找到解決方法：比較兩臺fw的cpconfig配置條目發現：

[NJZQ-CP-246]# expert

Enter expert password:

You are in expert mode now.

[Expert@NJZQ-CP-246]# cpconfig

(10) Exit

Enter your choice (1-10) :6  //這里選擇6，回車，將Advanced Routing 功能disable掉。

CP-248重啟后，查看cluster的狀態，立即恢復了正常。

[Expert@NJZQ-CP-248]# cphaprob stat

Cluster Mode:   New High Availability (Active Up)

Number    Unique Address  Assigned Load   State      

1         221.226.154.195 100%           Active     

2 (local) 19.19.19.248    0%              Standby     

[Expert@NJZQ-CP-248]#

查看CP-246，查看cluster狀態如下：

[Expert@NJZQ-CP-246]# cphaprob stat

Cluster Mode:   New High Availability (Active Up)

Number    Unique Address  Assigned Load   State      

1 (local) 19.19.19.246    100%            Active     

2         19.19.19.248    0%              Standby     

[Expert@NJZQ-CP-246]#

至此，兩臺CP防火墻的Cluster已經成功，主備倒換正常。
