Hi
In your case, It seems that ISP bgp setting seems to wrong.
but If ping dst IP is belong to just one ISP, dst unreachable is expected result.
First, ping to google(belong to lots of ISP), unplug one ISP, stop ping and retry ping.
Second, check ISP`s bgp hold time. -> normally long as you expected.
thank you.

I opened tech case, it seems the normal behavior on F5.
It looks you kept the ping tool running all the time. This should not exist if you stop the command and then run it again after 10 seconds. This is due to that even for ICMP traffic, there will be a connection established in connection table. The entry in the connection table won't be removed even if the member is down.
That's ok just need to explain to customer.
