Referring to the exhibit, the GRE tunnel between R-1 and R2 allows connectivity between User-1 and Server-1. User-1 can communicate with Server-1 with packets that are up to 1448 bytes in size.
However, if the packet size is larger than 1448, User-1 cannot communicate with Server-1.
In this scenario, how do you solve the communication problem?
