Error with OSPF route

Question

Hi Sophos. 
 I have configured Sophos Firewall OSPF with Cisco via a leased line . 
 two sites can ping each other. Sophos Neighbor ospf table have information about cisco 
 The problem is that when i turn on ospf route in Sophos firewall. I have tested ping on the Sophos site. Ping will drop 50%-75% of the packet and reply time from 2000ms to 3000ms , when i ping lan network or isp ip. 
 Log view table shows a lot of drop packets from 0.0.0.0 to 0.0.0.0 with a message. "ip packet with invalid header version " 
 when i turn off ospf. ping with isp and lan network is ok. 
 does anyone have idea what is that with ospf?

Hi Tri Nguyen2 
 Please share output for the following : 
 Please get access to CLI as per the link . Go to Option 3 (Route Configuration) > Option 1 (Configure Unicast Routing) > Option 2 (Configure OSPF). Turn on OSPF by running the command console > enable. 
 ospf(config-router)# show running-config 
 From option 4 : 
 Run the command tcpdump 'proto 89' 
 Run the command tcpdump 'host 224.0.0.5' 
 Check any drop from Sophos XG or not
