  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?

  A. Change the physical MTU on the ge-0/0/3 interfaces on R-1 and R-2 to 1448 bytes.

  B. Change the physical MTU on the gr-0/0/0 interfaces on R-1 and R-2 to 1448 bytes.

  C. Apply the allow-fragmentation statement to the GRE tunnel configuration.

  D. Apply the path-mtu-discovery statement to the GRE tunnel configuration.

  Correct Answer: C

  A. Router R1 must be configured as a stub area for Area 0.0.0.0.

  B. Router R1 will send a default route to router R2.

  C. Router R2 will not have a route to subnet 172.16.4.0/24.

  D. Router R3 will not have a route to subnet 172.16.3.0/24.
