In the diagram shown below, L1 is an Ethernet LAN and L2 is a Token Ring LAN. An IP packet originates from sender S and traverses to R, as shown. The links within each ISP and across the two ISPs, are all point to point optical links. The initial value of the TTL field is 32. The maximum possible value of the TTL field when R receives the datagram is ________.
-
- 26
- 16
- 6
- 36
Correct Option: A
Initial value of TTL field is 32. Except R, all nodes will decrement the TTL value.
∴ TTL value when packet is received at R = 32 – 6 = 26
