You have configured IPv6 over IPv4 tunneling, as shown in the exhibit. However, hosts connected to network 2001:0:0:1::0/64 cannot communicate with hosts on network 2001:0:0:2::0/64. The router R2 has a similar configuration as the R1 router.
How would you solve this problem?

• A.Configure an IGP across the tunnel interfaces
• B.Configure an IPv6 address on the tunnel interfaces
• C.Configure the next hop of the inet6.0 static route to point to the physical interface between the routers
• D.Configure the next hop of the inet6.0 static route to point to the IPv4 address of the remote router

Referring to the exhibit, the GRE tunnel between R-1 and R-2 allows connectivity between User-1 and Server-1. When User-1 communicates with Server-2 with packets that are 1472 bytes in size, no packet fragmentation occurs. User-1 can communicate with Server-1 with packets that are up to 1448 bytes in size with no packet fragmentation. However, if the packet size is larger than 1448 bytes, packet fragmentation occurs.
Why is the packet fragmentation occurring between User-1 and Server-1 in this scenario?

• A.The GRE header adds 20 bytes to the packet
• B.The GRE header adds 24 bytes to the packet
• C.The IP header adds 20 bytes to the packet
• D.The IP header adds 24 bytes to the packet
