I created a Logical interface using my VPN Application and added the default route - in routing table as my logical interface.
To Add the default route programmatically, I have to delete the existing default and then to add.
Once added, the system is updating the routing table with the default entry of the physical interface in the following two scenarios.
When the machine is rebooted or its the first time launching of the VPN application --- the system is taking exactly 65 seconds to update the routing table with the default route entry of the physical interface.
In other normal cases --- the system is immediately updating the routing table with the default route entry of the physical interface once the application has added the route entry for the logical interface.
Due the 65sec delay, the system is losing internet connectivity for 65 seconds.
Is there any solution to overcome this delay?
Or is it the default behaviour of MAC?
I tried flushing the arp tables and routing tables also but still the delay persists.
