A few questions, I'm trying to narrow the search area.

 

Can you confirm your issue is that as you're trying to ping the Floating-SelfIP (172.19.68.5) from one of the VMs in same network, there's no response? If yes, have you tried using tcpdump on BigIP yet - do you see ICMP echo requests coming in, and if not, do you see any ARP who-is requests? Is the situation any better with the Local-SelfIP (172.19.68.4) - does it respond to ICMP as intended?
