After adding RTR_2 router, no routing updates are being exchanged between RTR_1 and the new location. All other inter connectivity and internet access for the existing locations of the company are working properly., D5 {4 R" G r: m
The task is to identify the fault(s) and correct the router configuration to provide full connectivity between the routers.
