Hello All,
I want to confirm for how long the data plane tunnel can survive to forward user traffic when the CONTROL connection down? I am experiencing traffic disruption when I lost the connection to controller due to link problem (or even controller shutdown).
As far as I know from some Cisco Live slides, the IPSec rekey will be happened within 24 hours and OMP caching is about 12 hours by default. So, I assume that user traffic will be still forwarded before the new key is distributed from vSmart to vEdge devices although we lost Controller connection.
I have tried to modify the rekey timer from 24hrs to 72hrs, however I'm still getting lost traffic (just about 1-2 hours) since the controller is DOWN.
I noticed from this capture below, there are routes received but NO routes are installed when vSmart is unreachable/DOWN:

Is there any value / parameters in Viptela need to be adjusted so that we can safe data plane tunnel (user traffic) at least for 2-3 days when CONTROLLER unreachable at any reason?
