What is true about the Hop Limit field in the IPv6 header?
What is true about the Hop Limit field in the IPv6 header?
The Hop Limit field in the IPv6 header is similar to the Time to Live (TTL) field in the IPv4 header. Its primary function is to prevent packets from circulating endlessly in the network. Each router that forwards the packet decreases the value of the Hop Limit field by one. If the Hop Limit field reaches zero, the packet is discarded, ensuring it does not loop indefinitely.
Replaces the time to live field of IPv4. This value is decremented by one at each forwarding node and packet discarded if it becomes 0

Il tuo sarcasmo mi uccide :-)
Agreed! TTL / Hop Limit is useful when you don't want packets looping around the network infinitely! Because, this will congest, slow and may crash if it cannot support the data load.
What kind of question is this? Is it a real LPI 102-500 question? Ridiculous to ask this question to people.
Hop Limit The Hop Limit field indicates the maximum number of links over which the IPv6 packet can travel before being discarded The Hop Limit field is similar to the IPv4 TTL field except that there is no historical relation to the amount of time (in seconds) that the packet is queued at the router.
Yes, that statement is true. The Hop Limit field in the IPv6 header is decremented by each router that forwards the packet. As the packet traverses through the network, the Hop Limit is reduced by one at each hop. If the Hop Limit field reaches zero, the packet is discarded, preventing it from circulating indefinitely and avoiding potential routing loops. This mechanism helps ensure that packets have a limited lifetime and don't endlessly circulate in the network.
