We have two sites coimbatore and Hyderabad, we have 1 Internet router and 1 MPLS router at each site.
In Coimbatore static router is running among core, internet and MPLS router.
In Hyderabad OSPF is running among core, internet and MPLS router.
In both the sites MPLS link is using as a primary link and internet router is using as a backup.
Now, the customer needs to switch the traffic from
MPLS router to Internet router [if the MPLS router goes down] with minimum delay.
At present, it is switching to INternet router with 35 sec approx. delay.
Is it possible to decrease the delay time under static and OSPF routing?
Diagram is duly attached.
