Dear admin,

One day, after integration between GGSN and Firewall, the services are down. I did not understand what the problem was actually. It made me very hopeless. After visiting Huawei Support website, I found my solution which was great relief for me.

The solution was  given below :

OSPF network type must be match between GGSN and Firewall

Before analyzing, I have ask customer about network type but the confirm that network type is P2P in both 2 side,

but finally i check that Firewall is still broadcast type. Some time we should not trust peer side, It is better if we can make sure from the log file.

 

Thanks to Huawei team

excellent...
