After webex session with F5 support today
We still don't know the root cause.
From my point of view,
It's may be a bug because after add F5 peer unit, Local unit can't establish iquery connection to peer unit , (peer unit also can't connect to local unit)
What strange is , we type command "tcpdump -nni Internal tcp port 4353" and try to "telnet peer 4353",... But no traffic show in tcpdump ??? It's mean F5 didn't even try to send packet from this port. But From "tmsh run /cm sniff-updates", we can see daemon want to send packet to peer unit. :(
So sync status still disconnect and we struck :(
Just update to all of you
